xfs: support logging EFIs for realtime extents
Teach the EFI mechanism how to free realtime extents. We're going to
need this to enforce proper ordering of operations when we enable
realtime rmap.
Declare a new log intent item type (XFS_LI_EFI_RT) and a separate defer
ops for rt extents. This keeps the ondisk artifacts and processing code
completely separate between the rt and non-rt cases. Hopefully this
will make it easier to debug filesystem problems.
