drm/i915: Add *_ring_begin() to request allocation
Now that the *_ring_begin() functions no longer call the request allocation code, it is finally safe for the request allocation code to call *_ring_begin(). This is important to guarantee that the space reserved for the subsequent i915_add_request() call does actually get reserved. v2: Renamed functions according to review feedback (Tomas Elf). For: VIZ-5115 Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
