Subject: USB: visor: fix null-deref at probe

From: Johan Hovold <[email protected]>

commit cac9b50b0d75a1d50d6c056ff65c005f3224c8e0 upstream.

Fix null-pointer dereference at probe should a (malicious) Treo device lack the expected endpoints.

Specifically, the Treo port-setup hack was dereferencing the bulk-in and interrupt-in urbs without first making sure they had been allocated by core.
