David Sterba 20a7db8ab3 btrfs: add dummy callback for readpage_io_failed and drop checks
Make extent_io_ops::readpage_io_failed_hook callback mandatory and
define a dummy function for btrfs_extent_io_ops. As the failed IO
callback is not performance critical, the branch vs extra trade off does
not hurt.
