Patch for regression with fix for CVE-2017-9375

Hi,

I tried to launch a VM running RedoxOS using the command given here: https://doc.redox-os.org/book/getting_started/try_vm.html, ie:
"""
qemu-system-x86_64 -serial mon:stdio -d cpu_reset -d guest_errors -smp 4 -m 1024 -s -machine q35 -device ich9-intel-hda -device hda-duplex -net nic,model=e1000 -net user -device nec-usb-xhci,id=xhci -device usb-tablet,bus=xhci.0 -enable-kvm -cpu host -drive file=redox_0.5.0_harddrive.bin,format=raw
"""

The result was:
"""
qemu-system-x86_64: /home/iurt/rpmbuild/BUILD/qemu-2.8.1.1/hw/usb/hcd-xhci.c:2161: xhci_kick_epctx: Assertion `!epctx->kick_active' failed.
Aborted (core dumped)
"""

When I search for a solution, I found this bug: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1718222 (CVE-2017-9375 fix cause qemu crash).

I finally found the attached patch (from Debian) and I rebuilt locally qemu with that patch. Using the packages I built solve the issue.

Best regards,

Nico.
