block: use proper return value from bio_failfast()

[ Upstream commit f3ca73862453ac1e64fc6968a14bf66d839cd2d8 ]

kernel test robot complains about a type mismatch:

   block/blk-merge.c:984:42: sparse:     expected restricted blk_opf_t const [usertype] ff
   block/blk-merge.c:984:42: sparse:     got unsigned int
   block/blk-merge.c:1010:42: sparse: sparse: incorrect type in initializer (different base types) @@     expected restricted blk_opf_t const [usertype] ff @@     got unsigned int @@

   block/blk-merge.c:1010:42: sparse:     got unsigned int

because bio_failfast() is return an unsigned int rather than the
appropriate blk_opt_f type. Fix it up.
