Use the block layer helper to initialize the common fields of tag_set such as blk_mq_ops, number of h/w queues, queue depth, command size, numa_node, timeout, BLK_MQ_F_XXX flags, driver data. This initialization is spread all over the block drivers. This avoids the code repetation of the inialization code of the tag set in current block drivers and any future ones.
