Revert "channel-usbredir: Fix crash on channel-up"
This reverts commit 291f3e44. Follow up patch should address rhbz#1399838 mentioned in commit above in a different way. Major reason to revert is that the SpiceUsbDeviceManager object is kept in SpiceSession as an easy way to share it between different SpiceUsbredirChannel while SpiceSession itself does not use it. This causes problems on migration as we start a new session with a new SpiceUsbDeviceManager object while the previous one still exists.
