[PATCH] usb: dwc3: remove 'pm_runtime_set_active' in resume callback

'pm_runtime_set_active' sets a flag to describe rumtime status.
This flag is automatically set in pm_runtime_get_sync/put_sync API.
'pm_runtime_set_active' checks the runtime status of parent device.
As a result, the below error message is printed.
dwc3 11110000.dwc3: runtime PM trying to activate child device
11110000.dwc3 but parent (11110000.usb) is not active.
