xfs: implement ->notify_failure() for XFS
Introduce xfs_notify_failure.c to handle failure related works, such as
implement ->notify_failure(), register/unregister dax holder in xfs, and
so on.
If the rmap feature of XFS enabled, we can query it to find files and
metadata which are associated with the corrupt data. For now all we do is
kill processes with that file mapped into their address spaces, but future
patches could actually do something about corrupt metadata.
After that, the memory failure needs to notify the processes who are using
those files.
