Chris Wilson 97f0615800 drm/i915: Pull seqno started checks together ...

We have a few instances of checking seqno-1 to see if the HW has started
the request. Pull those together under a helper.

v2: Pull the !seqno assertion higher, as given seqno==1 we may indeed
check to see if we have started using seqno==0.
