xfs: introduce a new xfs_inode_has_cow_data helper
We have a few places that already check if an inode has actual data in the COW fork to avoid work on reflink inodes that do not actually have outstanding COW blocks. There are a few more places that can avoid working if doing the same check, so add a documented helper for this condition and use it in all places where it makes sense.
