usb: dwc3: ep0: Reset TRB counter for ep0 IN
commit f035d139ffece7b6a7b8bfb17bd0ba715ee57a04 upstream.
DWC3 tracks TRB counter for each ep0 direction separately. In control
read transfer completion handler, the driver needs to reset the TRB
enqueue counter for ep0 IN direction. Currently the driver only resets
the TRB counter for control OUT endpoint. Check for the data direction
and properly reset the TRB counter from correct control endpoint.
