block: use enum type for blk_mq_alloc_data->rq_flags

kernel test robot reports that we now trigger some sparse warnings:

block/blk-mq.h:169:32: sparse: sparse: restricted req_flags_t degrades to integer
block/blk-mq.h:169:32: sparse: sparse: restricted req_flags_t degrades to integer
block/blk-mq.h:169:32: sparse: sparse: restricted req_flags_t degrades to integer

which is due to ->rq_flags being an unsigned int, rather than the
stronger type req_flags_t enum.

Change the type to req_flags_t to silence this warning.
