scsi: sd_zbc: Fix sd_zbc_complete()
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.
[mkp: applied by hand]
