scsi: pm8001: Improve pm80XX_send_abort_all()

Both pm8001_send_abort_all() and pm80xx_send_abort_all() are called only
for a non null device with the NCQ_READ_LOG_FLAG set, so remove the device
check on entry of these functions. Furthermore, setting the
NCQ_ABORT_ALL_FLAG device id flag and clearing the NCQ_READ_LOG_FLAG is
always done before calling these functions. Move these operations inside
the functions.
