Sparse reports a warning at ata_scsi_rbuf_fill() and ata_scsi_rbuf_get()
warning: context imbalance in ata_scsi_rbuf_get() - wrong count at exit
warning: context imbalance in ata_scsi_rbuf_fill() - unexpected unlock
The root cause is the missing annotation at ata_scsi_rbuf_fill()
and ata_scsi_rbuf_get()
Add the missing __acquires(&ata_scsi_rbuf_lock)
Add the missing __releases(&ata_scsi_rbuf_lock)
