An USB wireless dongle uses rtl8712u stops working after system
suspend/resume.
When a USB device lost its power during suspend, the USB core knows the
power was lost and a reset-resume or a re-probe is required. But rtl8712u
provides a dummy reset-resume callback, which gets called and renders
the device dead after resume.
So remove the reset-resume call back, if power was lost during suspend,
let the USB core unbind and probe the device to solve the issue.
