block: don't lose track of REQ_INTEGRITY flag

Browse Source 
We need to pass bio->bi_opf after bio intergrity preparing, otherwise
the flag of REQ_INTEGRITY may not be set on the allocated request, then
breaks block integrity.

Fixes: f9afca4d36 ("blk-mq: pass in request/bio flags to queue mapping")
