scsi: sd_zbc: Let the SCSI core handle ILLEGAL REQUEST / ASC 0x21 

scsi_io_completion() translates the sense key ILLEGAL REQUEST / ASC 0x21 into
ACTION_FAIL. That means that setting cmd->allowed to zero in sd_zbc_complete()
for this sense code / ASC combination is not necessary. Hence remove the code
that resets cmd->allowed from sd_zbc_complete().
