In that case, does it make sense to remove the condition check

if (rxcb->peer_id)

in ath11k_dp_rx_h_find_peer()? It looks like this has been used as a
small optimisation, where if peer_id isn't valid it skips checking for
it in the peer hash table. However, if on newer chips peer_id=0 is
valid, we should remove this?
