Subject[ 036/117] USB: move usb_translate_errors to linux/usb.h
3.2-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Johan Hovold <jhovold@gmail.com>

commit 2c4d6bf295ae10ffcd84f0df6cb642598eb66603 upstream.

Move usb_translate_errors from usb core to linux/usb.h as it is meant to
be accessed from drivers.
