usb: dwc3: ep0: Don't reset resource alloc flag

Browse source

commit f2e0eee470 upstream.

The DWC3_EP_RESOURCE_ALLOCATED flag ensures that the resource of an
endpoint is only assigned once. Unless the endpoint is reset, don't
clear this flag. Otherwise we may set endpoint resource again, which
prevents the driver from initiate transfer after handling a STALL or
endpoint halt to the control endpoint.
