[SCSI] don't reference freed command in scsi_init_sgtable
Patch
commit 0479633686d370303e3430256ace4bd5f7f138dc
Author: Christoph Hellwig <hch@infradead.org>

[SCSI] do not manipulate device reference counts in scsi_get/put_command
Introduced a use after free: when scsi_init_io fails we have to release our
device reference, but we do this trying to reference the just freed command.
Add a local scsi_device pointer to fix this.
