usb: gadget: tegra-xudc: fix PM use count underflow
Upon resume from system suspend, the PM runtime core issues the
following warning:
tegra-xudc 3550000.usb: Runtime PM usage count underflow!
This is because tegra_xudc_resume() unconditionally calls
schedule_work(&xudc->usb_role_sw_work) whether or not anything has
changed, which causes tegra_xudc_device_mode_off() to be called
even when we're already in that mode.
Keep track of the current state of "device_mode", and only schedule
this work if it has changed from the hardware state on resume.
