feckert - modemmanager: reconnect interface if the modemmanager detects a disconnect

openwrt:master ← TDT-AG:pr/20240305-modemmanager

There are situation for mobile routers, that the modemmanager can not stay conne…cted to the mobile network. There can have various reasons. In order for the system to reconnect automatically, the netifd must be informed that it must re-establish the connection. The modem manager already does have a script callback handling which is already used by the modemmanager in openwrt. Currently the modem is marked as not unavailable when a disconnected event is detected. The behavior was changed with this commit, so that a reconnect of the interface is now triggerd via the netifd if the modem disconnects. Signed-off-by: Florian Eckert <fe@dev.tdt.de>

So automatic reconnection in ModemManager should be the norm now.
