SystemUI: Reset the cache state when registering the listener
FiveGServiceClient is a single instance, 5G icon state will
be received and cached even with no listener.
5G icon state depends on modem, FiveGStateListener registering
depends on telephony. In some race case, 5G icon state is
earlier than the listener registering, which leads to 5G icon
state not notify to UI
As the client will query 5G icon state after registering
listener,so reset the cache state when registering listener
to avoid race issue
