usb: xhci: fix duplicate stall handling in handle_tx_event()

Browse Source 
Stall handling is managed in the 'process_*' functions, which are called
right before the 'goto' stall handling code snippet. Thus, there should
be a return after the 'process_*' functions. Otherwise, the stall code may
run twice.
