erofs: set error to bio if file-backed IO fails

Browse Source 
[ Upstream commit 1595f15391b81815e4ef91c339991913d556c1b6 ]

If a file-backed IO fails before submitting the bio to the lower
filesystem, an error is returned, but the bio->bi_status is not
marked as an error. However, the error information should be passed
to the end_io handler. Otherwise, the IO request will be treated as
successful.
