[Intel-gfx] [PATCH 43/59] drm/i915: Update ring->emit_request() to take a request structure

[John.C.Harrison at Intel.com]

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

Updated the ring->emit_request() implementation to take a request instead of a
ringbuf/request pair. Also removed it's use of the OLR for obtaining the
request's seqno.

For: VIZ-5115
