drm/i915: Fix tracing of submit seqno
We pre-increment the timeline->seqno when handing it to the request,
make sure the GEM_TRACE takes this into account. Otherwise, it appears
that we go backwards over a preemption point:
1d..1 157681077us : __i915_request_unsubmit: vcs0 fence 75e:3 <- global_seqno 17
0d.s1 157681113us : __i915_request_submit: vcs0 fence 75e:3 -> global_seqno 16
Fixes: d9b13c4dde6c ("drm/i915: Trace GEM steps between submit and wedging")
