USB: gadget: ci13xxx: fix complete() callback for no_interrupt rq's
CI13xxx UDC driver doesn't call complete() callback for requests
with flag no_interrupt set. Thus gadget drivers (like g_ether) are
never notifed about successfully (or not) transmitted requests. As
a result in case of g_ether and queued request with no_interrupt=1
fields g_ether is never notifed about sent packets and TX stalls.
Solution: treat no_interrupt flag like all other UDC drivers do and
call complete() callback for all requests.
