xfs: do not use xfs_mod_incore_sb for per-cpu counters
Export xfs_icsb_modify_counters and always use it for modifying the per-cpu counters. Remove support for per-cpu counters from xfs_mod_incore_sb to simplify it. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>
