Remove short socket timeout workaround for VM blocking problem

The svmpd event server in the VM has been fixed to no longer block on a
single connection, which previously prevented any new connections to that
VM if the old client connection was still lingering in a zombie state.

Now the VM will keep accepting new socket connections from the server,
each time kicking off whatever old previous connection might still be
shuffling around, so we don't need the short timeout workaround any
more.
