Subject: USB: iowarrior: fix info ioctl on big-endian hosts

From: Johan Hovold <[email protected]>

commit dd5ca753fa92fb736b1395db892bd29f78e6d408 upstream.

Drop erroneous le16_to_cpu when returning the USB device speed which is already in host byte order.

Found using sparse:

warning: cast to restricted __le16

Fixes 946b960d13c1 ("USB: add driver for iowarrior devices.")
