Btrfs: fix meta data raid-repair merge problem
Commit 4a54c8c16 introduced raid-repair, killing the individual readpage_io_failed_hook entries from inode.c and disk-io.c. Commit 4bb31e92 introduced new readahead code, adding a readpage_io_failed_hook to disk-io.c. The raid-repair commit had logic to disable raid-repair, if readpage_io_failed_hook is set. Thus, the readahead commit effectively disabled raid-repair for meta data. This commit changes the logic to always attempt raid-repair when needed and call the readpage_io_failed_hook in case raid-repair fails. This is much more straight forward and should have been like that from the beginning.
