Akinobu Mita 5781175fab blk-mq: avoid setting hctx->tags->cpumask before allocation ...

commit 1356aae083 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.
