[PATCH 23/33] xfs: remove xfs_reflink_end_cow_extent wrapper and rename locked variant

[Dave Chinner <dgc@kernel.org>]

Now that xfs_reflink_end_cow() calls xfs_reflink_end_cow_extent_locked()
directly with its rolling transaction, the xfs_reflink_end_cow_extent()
wrapper function is no longer needed. Remove it entirely and rename
xfs_reflink_end_cow_extent_locked() to xfs_reflink_end_cow_extent()
since there is no longer an unlocked variant.
