stub_disconnect() calls stub_device_reset() during usb_unbind_device() when
usb device is locked. So usb_lock_device_for_reset() in stub_device_reset()
in that case polls for one second and returns -EBUSY anyway.
Remove useless flag USBIP_EH_RESET from SDEV_EVENT_REMOVED.

Nope, it's the middle of the merge window, I can't do anything with new
patches until after 4.7-rc1 comes out. And even then, give me a week or
so to catch up...
thanks,
