xfs: optimize xfs_reflink_end_cow
Instead of doing a full extent list search for each extent that is
to be deleted using xfs_bmapi_read and then doing another one inside
of xfs_bunmapi_cow use the same scheme that xfs_bumapi uses: look
up the last extent to be deleted and then use the extent index to
walk downward until we are outside the range to be deleted.
