From: Sriram R <quic_srirrama@xxxxxxxxxxx> In RX WBM error path, error packet is received with invalid peer_id (0x3FFF) as there is no peer associated with that packet. However, this invalid peer_id coincides with the ML peer_id valid bit mask, causing an unnecessary search in the ML peer list. Prevent searching the peer list for invalid peer_id and return NULL.
