[XFS] Don't double count reserved block changes on UP.

Browse source 
On uniprocessor machines, the incore superblock is used for all in memory
accounting of free blocks. in this situation, changes to the reserved
block count are accounted twice; once directly and once via
xfs_mod_incore_sb(). Seeing as the modification on SMP is done via
xfs_mod_incore_sb(), make this the only update mechanism that UP uses as
well.
