scsi: sd: Unlock zone in case of error in sd_setup_write_same_cmnd()
scsi_io_init() may fail, leaving a zone of a zoned block device locked. Fix this by properly unlocking the write same request target zone if scsi_io_init() fails. Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
