scsi: snic: Fix possible UAF in snic_tgt_create()
[ Upstream commit e118df492320176af94deec000ae034cc92be754 ]
Smatch reports a warning as follows:
drivers/scsi/snic/snic_disc.c:307 snic_tgt_create() warn:
'&tgt->list' not removed from list
If device_add() fails in snic_tgt_create(), tgt will be freed, but
tgt->list will not be removed from snic->disc.tgt_list, then list traversal
may cause UAF.
Remove from snic->disc.tgt_list before free().
Fixes: c8806b6c9e82 ("snic: driver for Cisco SCSI HBA")
