Andrzej Pietrasiewicz 1ade5d7e17 usb: gadget: f_uac2: don't queue new requests when shutting down 
In some circumstances when g_audio is being unloaded there happens
an endless loop in udc driver. It has happend on a board with
s3c-hsotg. If there are requests in endpoint's queue, they are completed
in a loop. But completing them might cause appending new requests
to the queue. This patch causes agdev_iso_complete() to return immediately
if request's status is -ESHUTDOWN. If it does not return immediately,
then although the current request is removed from the queue, a new one
is appended to the queue, so the above mentioned loop cannot end.
