usb: usb-storage doesn't support dynamic id currently, the patch disables the feature to fix an oops

commit 1a3a026ba1b6bbfe0b7f79ab38cf991d691e7c9a upstream.

Echo vendor and product number of a non usb-storage device to
usb-storage driver's new_id, then plug in the device to host and you
will find following oops msg, the root cause is usb_stor_probe1()
refers invalid id entry if giving a dynamic id, so just disable the
feature.
