[PATCH wireless-next] wifi: mm81x: start beaconing on beacon enable not interface add

[samuele.yang@morsemicro.com]

From: Samuele Yang <samuele.yang@morsemicro.com>

Currently we only initialise and start the beaconing process when the
AP interface is first added. If the BSS alone is reconfigured and
beaconing is temporarily stopped, the subsequent call to re-enable
the beacon via BSS_CHANGED_BEACON_ENABLED is ignored and beaconing will
be permanently stopped until the interface is completely re-added.

To fix, move the beaconing start/stop to mm81x_mac_ops_bss_info_changed
and react accordingly to info->enable_beacon and just keep the per-vif
work item init in the add_interface callback.

Fixes: b1906cea00b0 ("wifi: mm81x: add mm81x Wi-Fi HaLow driver")
