gpu-compute, mem-ruby: Add p_popRequestQueue to some transitions
Two W->WI transitions, on events RdBlk and Atomic in the GPU L2 cache
coherence protocol do not clear the request from the request queue upon
completing the transition. This action is not performed in the respone
path. This update adds the p_popRequestQueue action to each of these
transitions to remove the stale request from the queue.
