According to IEEE Std 802.11-2024, subclause 11.45.2.1 FILS Discovery frame transmission, only a transmitting BSS shall transmit a FILS Discovery frame. Currently, BSS_CHANGED_FILS_DISCOVERY is set unconditionally for all the BSSs. Hence, add a check to allow setting the FILS Discovery flag only for a transmitting BSS. Similarly, IEEE Std 802.11-2024, subclause 26.17.2.3.2 AP behavior for fast passive scanning, mentions that unsolicited broadcast probe response frame shall be transmitted only by a transmitting BSS. Hence, add a check to allow setting the BSS_CHANGED_UNSOL_BCAST_PROBE_RESP only for a transmitting BSS.
