Fix the RMA based protocol (the only one we have) to correctly handle alpha channel when transferring slices.

Excluding the SHM provider from the tests for now, because the writer cannot handle multiple writes without completion queue reads in between. We intent to fix this later together with some other possible optimizations.

Fixes #592
