xfs: fix locking of the rt bitmap/summary inodes

When we're deleting realtime extents, we need to lock the summary
inode in case we need to update the summary info to prevent an assert
on the rsumip inode lock on a debug kernel.  While we're at it, fix
the locking annotations so that we avoid triggering lockdep warnings.
