Subject: USB: storage: properly handle the endian issues of idProduct
From: fangxiaozhi <huananhu@xxxxxxxxxx>
commit cd060956c5e97931c3909e4a808508469c0bb9f6 upstream.
1. The idProduct is little endian, so make sure its value to be
compatible with the current CPU. Make no break on big endian processors.
