altos: Clear callsign on initial config load

Before being written the first time, ao_config will get set to 0xff
when the config storage is read. This leaves the tail of the callsign
filled with invalid bytes. Zero the whole thing before loading the
default callsign to make sure any extra bytes are set correctly.
