Monitor mode is enabled by handling the filter flags we get from mac80211 in rtl8xxxu_configure_filter() and writing them to the RCR register. By handling these filters correctly we can also stop setting the BSSID filters in the association event. Also remove initial setting of the RCR register from rtl8723a_mac_init_table.
