The ILLEGAL REQUEST/INVALID FIELD IN CDB error generated by an attempt
to reset a conventional zone does not apply to the reset write pointer
command with the ALL bit set, that is, to REQ_OP_ZONE_RESET_ALL
requests. Fix sd_zbc_complete() to be quiet only in the case of
REQ_OP_ZONE_RESET, excluding REQ_OP_ZONE_RESET_ALL.
Since REQ_OP_ZONE_RESET is the only request handled by
sd_zbc_complete(), also simplify the code using a simple if statement.
