xfs: improve rt metadata use for scrub

This short series makes some small changes to the way we handle the
realtime metadata inodes.  First, we now make sure that the bitmap and
summary file forks are always loaded at mount time so that every
scrubber won't have to call xfs_iread_extents.  This won't be easy if
we're, say, cross-referencing realtime space allocations.  The second
change makes the ILOCK annotations more consistent with the rest of XFS.
