  erofs: fix bio->bi_max_vecs behavior change (2021-03-08 10:43:32 +0800)

----------------------------------------------------------------
Change since last update:

Fix an urgent regression introduced by commit baa2c7c97153 ("block:
set .bi_max_vecs as actual allocated vector number"), which could
cause unexpected hung since linux 5.12-rc1.

Resolve it by avoiding using bio->bi_max_vecs completely.
