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.
This patch depends on
commit 69e131d1ac4e ("usb: dwc3: gadget: Prevent repeat pullup()")
Fixes: 77adb8bdf422 ("usb: dwc3: gadget: Allow runtime suspend if UDC unbinded")
