iomap: simplify ->read_folio_range() error handling for reads

Browse source

Instead of requiring that the caller calls iomap_finish_folio_read()
even if the ->read_folio_range() callback returns an error, account for
this internally in iomap instead, which makes the interface simpler and
makes it match writeback's ->read_folio_range() error handling
expectations.
