Andrew Turner 7680515c07 Add a pmap invalidate that doesn't call sched_pin.
When demoting DMAP pages curthread may be pointing to data within the
page we are demoting. Create a new invalidate that doesn't pin and use
it in the demote case.

As the demote has both interrupts disabled, and is within a critical section
this is safe from having the scheduler from switching to another CPU.
