SCSI fixes on 20191111 

Three small changes: two in the core and one in the qla2xxx
 driver. The sg_tablesize fix affects a thinko in the migration to
 blk-mq of certain legacy drivers which could cause an oops and the sd
 core change should only affect zoned block devices which were wrongly
 suppressing error messages for reset all zones.
