If there's a need to reset the device, then we don't know for how
long it was unfunctional and the connection to the network is lost.
There's no point in resuming the device.
In theory we can do it, if the device was down anyway, but even then
no benefit is derived. If a btusb device used reset_resume(),
it would better be reenumerated anyway.
