Subject: [PATCH] lnd: close the wallet unlock grpc server

The server was kept alive long after it stopped being used. This caused
problems for services using long-lived GRPC connections which might be
created before wallet unlocked. They got stuck connected to the wallet
unlock service needing a restart.
