[PATCH 6/9] scsi: libsas: Add missing annotation for sas_ata_qc_issue()

[Jules Irenge]

Sparse reports a warning at sas_ata_qc_issue()

warning: context imbalance in sas_ata_qc_issue() - unexpected unlock
The root cause is the missing annotation at sas_ata_qc_issue()

Add the missing __must_hold(ap->lock) annotation
