The context owns both the ppgtt and the vma within it, and our activity
tracking on the context ensures that we do not release active ppgtt. As
the context fulfils our obligations for active memory tracking, we can
relinquish the reference from the vma.
This fixes a silly transient refleak from closed vma being kept alive
until the entire system was idle, keeping all vm alive as well.
