This is a follow-up to the series at [0] to fix SCSI device tagging and
use the per-device token as the libata qc tag.

I added the changes Christoph shared on the list to move
the functionality from ata_qc_new_init() into libata-scsi.c

Please do not apply on a kernel which does not include
"scsi: core: Fix sbitmap depth in scsi_realloc_sdev_budget_map()"

v5.18-rc2 should be the release to include that patch.
