Subject: [PATCH] usb: Remove annoying warning about bogus URB

When ath9k-htc Wi-Fi dongle is used with generic OHCI controller
infinite stream of warnings appears in debug console like this:
-------------------------->8----------------------

There're some discussions in mailing lists proposing to disable
that particular check alltogether and magically all seem to work
fine with muted warning.

Anyways new thread on that regard could be found here:
http://lists.infradead.org/pipermail/linux-snps-arc/2016-July/001310.html

Let's see what comes out of that new discussion, hopefully patching
of generic USB stuff won't be required then.
