FROMLIST: usb: dwc3: gadget: Avoid duplicate requests to enable Run/Stop

Relocate the pullups_connected check until after it is ensured that there
are no runtime PM transitions.  If another context triggered the DWC3
core's runtime resume, it may have already enabled the Run/Stop.  Do not
re-run the entire pullup sequence again, as it may issue a core soft
reset while Run/Stop is already set.
