USB: gadget: g_multi: fixed vendor and product ID in inf files

commit 7701846fd52f86dffe50715e0e63154088b7c982 upstream.

Commit 1c6529e92b "USB: gadget: g_multi: fixed vendor and
product ID" replaced g_multi's vendor and product ID with
proper ID's from Linux Foundation.  This commit now updates
INF files in the Documentation/usb directory which were
omitted in the original commit.
