wifi: rtw89: refine RX filter configuration for WiFi 7 generation

Browse source 
When an AP interface is registered and starts AP, mac80211 calls the
configure_filter() to clear B_AX_A_UC_CAM_MATCH and B_AX_A_BC_CAM_MATCH
so that frames from un-associated stations can be received. However, for
a dedicated AP interface created via iw command, configure_filter() is
only triggered on the initial AP startup. Since the interface remains up
even after hostapd stops, and it isn't triggered again on later restarts.
Additionally, each AP start causes IPS leave, reverting the RX filter to
its default value.

For WiFi 7 chips, the default value is hardcoded in rx_fltr_init_be(),
so the reverted value does not match hal.rx_fltr. Therefore, refine
the behavior of WiFi 7 chips to align with the WiFi 6 implementation.
