PM / Sleep: Drop suspend_stats_update()
Since suspend_stats_update() is only called from pm_suspend(), move its code directly into that function and remove the static inline definition from include/linux/suspend.h. Clean_up pm_suspend() in the process. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Srivatsa S. Bhat <srivatsa.bhat@linux.vnet.ibm.com>
