xfs: convert XFS_AGFL_SIZE to a helper function
The AGFL size calculation is about to get more complex, so lets turn the macro into a function first and remove the macro. Signed-off-by: Dave Chinner <dchinner@redhat.com> [darrick: forward port to newer kernel, simplify the helper] Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
