From: Victor Toso <m...@victortoso.com>
As spice_usbredir_channel_up() can be called when channel-usbredir is
not yet initialized, priv->host can be NULL leading to a crash in
usbredir.
See previous patch that does initialize SpiceUsbDeviceManager on
SpiceSession init and also the comment in 5b252b0f499601bcf387c02a4
which fix similar behavior.
We should simply log a critical message instead of crashing the
application.
