gobi-cromo-plugin: Undo udev hack partly.

I removed a call to RemoveDeviceByControlPath here, even though that call was
actually required. The udev event announcing that /dev/qcqmi0 is gone does not
mean that the sysfs file for the device is actually gone - the sysfs file
lingers as long as there are references to the device file held in kernelspace.
