xfs: pass xfsstats structures to handlers and macros
This patch is the next step toward per-fs xfs stats. The patch makes the show and clear routines able to handle any stats structure associated with a kobject. Instead of a single global xfsstats structure, add kobject and a pointer to a per-cpu struct xfsstats. Modify the macros that manipulate the stats accordingly: XFS_STATS_INC, XFS_STATS_DEC, and XFS_STATS_ADD now access xfsstats->xs_stats. The sysfs functions need to get from the kobject back to the xfsstats structure which contains it, and pass the pointer to the ->xs_stats percpu structure into the show & clear routines.
