ata: Annotate functions in the issuing path with __must_hold()
Annotate the following functions used in the issuing path:
ata_qc_issue(), ata_sas_queuecmd(), ata_scsi_qc_issue(),
ata_scsi_translate(), __ata_scsi_queuecmd()
These functions are all used in the issuing path, so context analysis will
be able to verify that the ap lock is held, from it is taken in
sas_queuecommand() or ata_scsi_queuecmd() all the way down to
ata_qc_issue().
Commenting out the spin_lock_irqsave() successfully results in a compiler
error on Clang 23.
