[Intel-gfx] [RFC 4/5] drm/i915: Drop GEM context reference while pinned

[Chris Wilson]

Ostensibly, as far recorded at least, we take a reference to our GEM
context parent to keep the ppgtt alive as long as we are pinned. Now
that the context holds a reference to the ppgtt itself, we should no
longer need the back reference.
