In monitor mode, the packet type is wrongly filled radiotap header as 11n when the actual incoming packet is 11b frame. The packet type field is common for all MPDUs and is obtained from PPDU_END_USER_STATS and hence no need to overwrite that value from the MPDU specific TLV in the function hal_rx_mon_hw_desc_get_mpdu_status Change-Id: I97f96e64012636f562f7ac2e4a91b63ffc7553db CRs-Fixed: 2333915
