powerpc/mm: Fix the call trace when resumed from hibernation
In SMP mode, the kernel would produce call trace when resumed from hibernation. The reason is when the function destroy_context is called to drop the resuming mm context, the mm->context.active is 1 which is wrong and should be zero. We pass the current->active_mm as previous mm context to function switch_mmu_context to decrease the context.active by 1. In UP mode, there is no effect.
