xfs: remove use of do_div with 32-bit dividend in quota

The kbuild test robot caught this; in debug code we have another caller of do_div with a 32-bit dividend (j) which is caught now that we are using the kernel-supplied do_div. None of the values used here are 64-bit; just use simple division. Signed-off-by: Eric Sandeen <[email protected]> Reviewed-by: Darrick J. Wong <[email protected]> Signed-off-by: Darrick J.
