qcacmn: Allow rx UDP packets during roaming before peer map is received

In VoIP cases, no or minimal packet drop is expected during
roaming. Currently, data packets are dropped in host if they
are received after roam sync indication from firmware and before
peer map indication is received due to invalid peer.
This change allows rx UDP data packets during roaming before
peer map indication is received from FW if peer's auth_status
received in roam_sync_indication from FW is authorised.
