net: uqmi: fix blocking in endless loops when unplugging device
If you unplug a QMI device, the /dev/cdc-wdmX device disappears but uqmi will continue to poll it endlessly. Then, when you plug it back, you have 2 uqmi processes, and that's bad, because 2 processes talking QMI to the same device [and the same time] doesn't seem to work well.
