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.
