Fix pre-commit.ci clang-format failures from PR #456 buffer management refactor

[Copilot]

PR #456 introduced buffer management and xskdev refactoring that repeatedly failed pre-commit.ci due to clang-format violations. The PR author's latest commit resolved these, and this PR carries those fixes forward.

Clang-format fixes applied to

• lib/core/pktmbuf/pktmbuf_offload.h — enum value alignment
• lib/core/xskdev/xskdev.c — variable alignment in fq_add()
• lib/include/cne_lport.h — #define macro alignment
• lib/usr/clib/dsa/cne_dsa.c — designated initializer alignment
• lib/usr/clib/utils/crc32.c — continuation line alignment
• test/testcne/acl_test_data.h — inline comment alignment

Substantive changes (from PR #456 HEAD)

• lib/core/pktmbuf/, lib/core/xskdev/, lib/include/cne_lport.h — buffer mgmt struct refactored to use mbuf_t typed callbacks; buf_headroom/buf_arg reorganized; unaligned_buff flag removed (unaligned path driven by LPORT_UMEM_UNALIGNED_BUFFERS flag)
• lib/usr/app/jcfg/ — parses new unaligned_buffers lport JSON key → LPORT_UMEM_UNALIGNED_BUFFERS
• lib/usr/slib/ibroker/meson.build — splits uintr_handler.c into a separate static lib built with -mtls-dialect=gnu2 to satisfy toolchain requirements
• examples/cndpfwd/ — replaces static frame bytes with proper RFC-conformant UDP/IP header construction
• tools/cne-build.sh — array-based meson args, improved quoting, minor message wording

Original prompt

Fix the pre-commit.ci validation failure for pull request #456 in repository CloudNativeDataPlane/cndp.

Context:

• PR: Refactor buffer management and update configuration handling #456
• Title: Refactor buffer management and update configuration handling
• The user specifically wants the pre-commit.ci problem fixed when validating the PR changes.

Task:

1. Inspect the pull request changes and determine why pre-commit.ci is failing.
2. Make the minimal code or formatting changes required to satisfy the pre-commit hooks.
3. Ensure the fix is limited to resolving the pre-commit.ci validation problem and does not introduce unrelated changes.
4. Open a pull request with the fix.

Notes:

• Use the existing repository and relevant branch context from PR Refactor buffer management and update configuration handling #456.
• If the failure is caused by formatting, linting, whitespace, YAML/TOML formatting, end-of-file newlines, or similar pre-commit hook issues, apply the canonical fix expected by pre-commit.
• If the failure is caused by a repository-specific hook, update the affected files accordingly.

The following is the prior conversation context from the user's chat exploration (may be truncated):
