lnd: only print shutdown message if logs are initialized

Browse Source 
In this commit, we fix a slight bug recently introduced by the addition
of the new signal package. As we now use a regular defer for many
actions, it may be possible that the logs aren't yet initialized (for
example, lnd -h), which can cause a panic if the shutdown procedure goes
to log before the logs have been initialized.
