ata: libata-scsi: refactor ata_scsi_translate()

commit bb3a8154b1a1dc2c86d037482c0a2cf9186829ed upstream.

Factor out of ata_scsi_translate() the code handling queued command
deferral using the port qc_defer callback and issuing the queued
command with ata_qc_issue() into the new function ata_scsi_qc_issue(),
and simplify the goto used in ata_scsi_translate().
While at it, also add a lockdep annotation to check that the port lock
is held when ata_scsi_translate() is called.

No functional changes.
