blk-mq: change gfp flags to GFP_NOIO in blk_mq_realloc_hw_ctxs

[ Upstream commit 5b202853ffbc54b29f23c4b1b5f3948efab489a2 ]

blk_mq_realloc_hw_ctxs could be invoked during update hw queues.
At the momemt, IO is blocked. Change the gfp flags from GFP_KERNEL
to GFP_NOIO to avoid forever hang during memory allocation in
blk_mq_realloc_hw_ctxs.
