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.

When ieee80211_restart_hw is called, all interfaces and stations are
recreated. This can lead to corruption in the sta poll list, since
existing entries were not removed before their private data is reset.

On MT7915, MCU hangs do not trigger watchdog interrupts, so they can only
be detected through MCU message timeouts. Ensure that the hardware gets
restarted when that happens in order to prevent a permanent stuck state.
