Subject: [PATCH 1/2] block: Delete bio_prio()

Since commit 43b62ce3ff0a ("block: move bio io prio to a new field"), macro
bio_prio() does nothing but return the value in bio->bi_ioprio. Most other
places just read bio->bi_ioprio directly, so replace bi_ioprio() callsites
with reading bio->bi_ioprio directly and delete that macro.
