wifi: mt76: mt7915: Fix mesh scan on MT7916 DBDC
[ Upstream commit f21b77cb556296116b1cce1d62295d13e35da574 ]
commit c4f075582304 ("wifi: mt76: mt7915: fix command timeout in AP stop
period") changes the behavior of mt7915_bss_info_changed() in mesh mode
when enable_beacon becomes false: it calls mt7915_mcu_add_bss_info(...,
false) and mt7915_mcu_add_sta(..., false) while the previous code
didn't. These sends mcu commands that apparently confuse the firmware.
This breaks scanning while in mesh mode on AsiaRF MT7916 DBDC-based cards:
scanning works but no mesh frames get sent afterwards and the firmware
seems to be hosed. It breaks on MT7916 DBDC but not on MT7915 DBDC.
