xfs: cleanup log reservation calculactions
Instead of having small helper functions calling big macros do the calculations for the log reservations directly in the functions. These are mostly 1:1 from the macros execept that the macros kept the quota calculations in their callers. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>

- * Most of the reservations underestimate the number of allocation

- * This will require changes to the EFI code as well, however, so that
