Andreas Kling 4bc3745ce6 Kernel: Make Region's physical page accessors safer to use ...

Region::physical_page() now takes the VMObject lock while accessing the
physical pages array, and returns a RefPtr<PhysicalPage>. This ensures
that the array access is safe.

Region::physical_page_slot() now VERIFY()'s that the VMObject lock is
held by the caller. Since we're returning a reference to the physical
page slot in the VMObject's physical page array, this is the best we
can do here.
