drm/i915/guc: Skip port assign on first iteration of GuC dequeue
If port[0] is occupied and we're trying to dequeue request from
different context, we will inevitably hit BUG_ON in port_assign.
Let's skip it - similar to what we're doing in execlists counterpart.
Fixes: 77f0d0e925e8a0 ("drm/i915/execlists: Pack the count into the low bits of the port.request")
