[Intel-gfx] [PATCH 07/13] drm/i915: kill an no longer necessary BUG_ON

[Daniel Vetter]

i915_gem_object_move_to_active can handle zero seqno's for us now.
And not emitting a request is not fatal here - we'll try to emit
a new one if we have to wait for some rendering to complete.

In case this assumption ever gets accidently broken, there's already
a BUG_ON to catch it in i915_do_wait_request.

So just silently ignore ENOMEM here instead of screwing up the whole
drm.
