block: remove spurious uses of REQ_HARDBARRIER
REQ_HARDBARRIER is deprecated. Remove spurious uses in the following users. Please note that other than osdblk, all other uses were already spurious before deprecation. * osdblk: osdblk_rq_fn() won't receive any request with REQ_HARDBARRIER set. Remove the test for it. * pktcdvd: use of REQ_HARDBARRIER in pkt_generic_packet() doesn't mean anything. Removed. * aic7xxx_old: Setting MSG_ORDERED_Q_TAG on REQ_HARDBARRIER is spurious. Removed. * sas_scsi_host: Setting TASK_ATTR_ORDERED on REQ_HARDBARRIER is spurious. Removed. * scsi_tcq: The ordered tag path wasn't being used anyway. Removed.
