Damien Le Moal 371b74c8ba ata: libata-sata: Simplify ata_change_queue_depth() ...

Commit 141f3d6256 ("ata: libata-sata: Fix device queue depth control")
added a struct ata_device argument to ata_change_queue_depth() to
address problems with changing the queue depth of ATA devices managed
through libsas. This was due to problems with ata_scsi_find_dev() which
are now fixed with commit 7f875850f2 ("ata: libata-scsi: Use correct
device no in ata_find_dev()").

Undo some of the changes of commit 141f3d6256: remove the added struct
ata_device aregument and use again ata_scsi_find_dev() to find the
target ATA device structure. While doing this, also make sure that
ata_scsi_find_dev() is called with ap->lock held, as it should.

libsas and libata call sites of ata_change_queue_depth() are updated to
match the modified function arguments.
