usb: cdnsp: Fixes issue with redundant Status Stage

Browse source

In some cases, driver trees to send Status Stage twice.
The first one from upper layer of gadget usb subsystem and
second time from controller driver.
This patch fixes this issue and remove tricky handling of
SET_INTERFACE from controller driver which is no longer
needed.
