drm/i915: Do not call drm_crtc_arm_vblank_event in async flips
Since the flip done event will be sent in the flip_done_handler,
no need to add the event to the list and delay it for later.
v2: -Moved the async check above vblank_get as it
was causing issues for PSR.
v3: -No need to wait for vblank to pass, as this wait was causing a
16ms delay once every few flips.
v4: -Rebased.
v5: -Rebased.
v6: -Rebased.
v7: -No need of irq disable if we are not doing vblank evade. (Ville)
v8: -Rebased.
v9: -Move the return in intel_pipe_update_end before tracepoint. (Ville)
v10: Rebased.
