libxfs: clean up _calc_dquots_per_chunk

[ Upstream commit 58d789678546d46d7bbd809dd7dab417c0f23655 ]

The function xfs_calc_dquots_per_chunk takes a parameter in units
of basic blocks.  The kernel seems to get the units wrong, but
userspace got 'fixed' by commenting out the unnecessary conversion.
Fix both.
