USB: dwc3: fix runtime pm imbalance on unbind

Browse Source 
commit 44d257e901 upstream.

Make sure to balance the runtime PM usage count on driver unbind by
adding back the pm_runtime_allow() call that had been erroneously
removed.

Fixes: 266d049390 ("usb: dwc3: core: don't trigger runtime pm when remove driver")
