libata: fix NULL sdev dereference race in atapi_qc_complete()
commit 2a5f07b5ec098edc69e05fdd2f35d3fbb1235723 upstream.
SCSI commands may be issued between __scsi_add_device() and dev->sdev
assignment, so it's unsafe for ata_qc_complete() to dereference
dev->sdev->locked without checking whether it's NULL or not. Fix it.
