xfs: hoist freeing of rt data fork extent mappings
Currently, xfs_bmap_del_extent_real contains a bunch of code to convert
the physical extent of a data fork mapping for a realtime file into rt
extents and pass that to the rt extent freeing function. Since the
details of this aren't needed when CONFIG_XFS_REALTIME=n, move it to
xfs_rtbitmap.c to reduce code size when realtime isn't enabled.
This will (one day) enable realtime EFIs to reuse the same
unit-converting call with less code duplication.
