Prevent infinite loop in X2GoRevFwTunnel handler
Without this change, we observed a running X2Go session freezing after about 3
hours running on Windows with the following output:
WARN: Reverse tunnel <paramiko.Channel 16 (open) window=2036405 ->
<paramiko.Transport at 0x4e4f270L (cipher aes128-ctr, 128 bits) (active; 2 open
channel(s))>> encoutered socket error: [Errno 10054] An existing connection was
forcibly closed by the remote host
Breaking after catching 1024 socket errors prevents looping forever. The
tunnel is automatically closed, which allows the application to reopen it
automatically and recover gracefully from the situation.
