block: skip unnecessary checks for split bio

Browse source

[ Upstream commit 0b64682e78 ]

Lots of checks are already done while submitting this bio the first
time, and there is no need to check them again when this bio is
resubmitted after split.

Hence open code should_fail_bio() and blk_throtl_bio() that are still
necessary from submit_bio_split_bioset().
