[Spice-devel] [PATCH] Revert "usbredir: Disconnect USB device asynchronously"

[Qiu Wenbo]

This reverts commit 9fbf679453d8dbfe797a738cb536136599d7adab.

In some cases, remote-viewer will exit before the async function run in
another thread finish and USB devices redirected to the VM will not "pop up" to
operation system. For example, a USB disk should be auto mounted
when remote-viewer exit.
