Harald Welte a14616c096 usb_buf: Limit the maximum queue length to 3 elements ...

If there are already three elements in the to-be-transmitted queue
for the EP, let's free the first element of the queue.  This is a
clear indication that the USB host is not polling the endpoint
regularly.  Maybe there's no host application running at all?

This should obsolete Change-Id Ie9ebdd2ff966f67c9afd1ed760f106558f0091ad
