usb: dwc3: don't reset device side if dwc3 was configured as host-only
commit e835c0a4 upstream. Commit c4a5153e ("usb: dwc3: core: Power-off core/PHYs on system_suspend in host mode") replaces check for HOST only dr_mode with current_dr_role. But during booting, the current_dr_role isn't initialized, thus the device side reset is always issued even if dwc3 was configured as host-only. What's more, on some platforms with host only dwc3, aways issuing device side reset by accessing device register block can cause kernel panic.
