block: refactor bio_iov_bvec_set()

Browse source

Combine bio_iov_bvec_set() and bio_iov_bvec_set_append() and let the
caller to do iov_iter_advance(). Also get rid of __bio_iov_bvec_set(),
which was duplicated in the final binary, and replace a weird
iov_iter_truncate() of a temporal iter copy with min() better reflecting
the intention.
