sata_mv: simplify request/response queue handling
Try and simplify handling of the request/response queues.
Maintain the cached copies of queue indexes in a fully-masked state,
rather than having each use of them have to do the masking.
Split off handling of a single crpb response into a separate function,
to reduce complexity in the main mv_process_crpb_entries() routine.
Ignore the rarely-valid error bits from the crpb status field,
as we already handle that information in mv_err_intr().
For now, preserve the rest of the original logic.
A later patch will deal with fixing that separately.
