[SCSI] bug fix for free list handling

    [SCSI] fix SLUB WARN_ON

Fixed another problem in free list handling by moving list allocation
from scsi_host_alloc() to scsi_add_host().  Unfortunately it
introduced a new failure mode in that hosts can pass straight from
alloc to put without going through add, leaving the free list
uninitialised.

Fix by checking shost->cmd_pool on the release path to see if it got
initialised.
