[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.
