Martin Wilck 03b75e65ce scsi: scsi_dh_rdac: zero cdb in send_mode_select() ... commit 57adf5d4cf upstream. cdb in send_mode_select() is not zeroed and is only partially filled in rdac_failover_get(), which leads to some random data getting to the device. Users have reported storage responding to such commands with INVALID FIELD IN CDB. Code before commit 3278255741 was not affected, as it called blk_rq_set_block_pc(). Fix this by zeroing out the cdb first. Identified & fix proposed by HPE.
