drm/i915: Convert 'last_flip_req' to be a request not a seqno

Browse source

Converted 'last_flip_req' to be an actual request rather than a seqno value as
part of the on going seqno to request changes. This includes reference counting
the request being saved away to ensure it can not be retired and freed while the
overlay code is still waiting on it.
