[Intel-gfx] [PATCH 26/59] drm/i915: Update init_context() to take a request structure

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

Now that everything above has been converted to use requests, it is possible to
update init_context() to take a request pointer instead of a ring/context pair.
