[patch 026/101] USB HID: Fix USB vendor and product IDs endianness for USB HID devices

[PATCH] USB HID: Fix USB vendor and product IDs endianness for USB HID devices

The USB vendor and product IDs are not byteswapped appropriately, and
thus come out in the wrong endianness when fetched through the evdev
using ioctl() on big endian platforms.
