blk-mq: Add a NULL check in blk_mq_free_map_and_requests()
I recently found some code which called blk_mq_free_map_and_requests()
with a NULL set->tags pointer. I fixed the caller, but it seems like a
good idea to add a NULL check here as well. Now we can call:
blk_mq_free_tag_set(set);
blk_mq_free_tag_set(set);
twice in a row and it's harmless.
