As a step towards freeing the PG_error flag for other uses, change ext4 and f2fs to stop using PG_error to track verity errors. Instead, if a verity error occurs, just mark the whole bio as failed. The coarser granularity isn't really a problem since it isn't any worse than what the block layer provides, and errors from a multi-page readahead aren't reported to applications unless a single-page read fails too. f2fs supports compression, which makes the f2fs changes a bit more complicated than desired, but the basic premise still works. Note: there are still a few uses of PageError in f2fs, but they are on the write path, so they are unrelated and this patch doesn't touch them.
