It has been observed that on certain chipsets a peer can be assigned
peer_id=0. For reception of non-aggregated MPDUs this is fine as
ath11k_dp_rx_h_find_peer() has a fallback case where it locates the peer
based upon the source MAC address. On an aggregated link, the mpdu_start
header is only populated by hardware on the first sub-MSDU. This causes
the peer resolution to be skipped for the subsequent MSDUs and the
encryption type of these frames to be set to an incorrect value,
resulting in these MSDUs being dropped by ieee80211.

Remove the null peer_id checks in ath11k_dp_rx_h_find_peer() and
ath11k_hal_rx_parse_mon_status_tlv(), allowing peers with an assigned ID
of 0 to be resolved.
