GUACAMOLE-1242: Move "connection closed" log message to debug level.
It is expected under normal circumstances that the connection may be
abruptly closed, including during the handshake. For example, this will
commonly occur when a TCP load balancer is performing a simple service
health check.
An message noting that the connection has been closed during the
Guacamole protocol handshake is really only of benefit when debugging,
where that information may provide useful context. If not debugging, the
message amounts to log noise.
