The checksum format is orthogonal to whether the protection information
is being passed on beyond the HBA or not.  It is perfectly valid to use
a non-T10 CRC with WRITE_STRIP and READ_INSERT.

Consequently it no longer makes sense to explicitly refer to the
conversion in the protection operation.  Update sd_dif and lpfc
accordingly.
