blk-mq: avoid setting hctx->tags->cpumask before allocation
commit 1356aae08338f1c19ce1c67bf8c543a267688fc3 upstream.
When unmapped hw queue is remapped after CPU topology is changed,
hctx->tags->cpumask has to be set after hctx->tags is setup in
blk_mq_map_swqueue(), otherwise it causes null pointer dereference.
Fixes: f26cdc8536 ("blk-mq: Shared tag enhancements")
