PM: hibernate: Fix hybrid-sleep
Hybrid sleep will hibernate the system followed by running through
the suspend routine. Since both the hibernate and the suspend routine
will call pm_restrict_gfp_mask(), pm_restore_gfp_mask() must be called
before starting the suspend sequence.
Add an explicit call to pm_restore_gfp_mask() to power_down() before
the suspend sequence starts. Add an extra call for pm_restrict_gfp_mask()
when exiting suspend so that the pm_restore_gfp_mask() call in hibernate()
is balanced.
