[SCSI] scsi_scan: add missing interim SDEV_DEL state if slave_alloc fails
We were running i/o and performing a bunch of hba resets in a loop. This forces a lot of target removes and then rescans. Since the resets are occuring during scan it's causing the scan i/o to timeout, invoking error recovery, etc. We end up getting some nasty crashing in scsi_scan.c due to references to old sdevs that are failing but had some lingering references that kept them around. Fix by setting device state to SDEV_DEL if the LLD's slave_alloc fails. Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
