mesa: Drop incorrect A4B4G4R4 _mesa_format_matches_format_and_type() cases.

swapBytes operates on bytes, not 4-bit channels, so you can't just take
non-swapBytes cases and flip the REV flag.

Avoids piglit texture-packed-formats regressions when enabling the
ABGR4444 format.

Fixes: c5a5c9a7db89 ("mesa/formats: add new mesa formats and their pack/unpack functions.")
