[Spice-devel] [PATCH v8 19/20] test-cd-emu: Make sure we can call spice_usb_backend_channel_flush_writes

[Victor Toso]

From: Frediano Ziglio <fziglio at redhat.com>

Currently we call this function when the SPICE channel is up
however this function should continue to work as in theory
the channel could avoid to handle the message and stop the flow
(for instance to implement some kind of flow limitation)
and so will need to call this function again.
This was failing in the first USB emulation implementation
causing a crash.
