usb: cdc-acm: make sure a refcount is taken early enough
commit c52873e5a1ef72f845526d9f6a50704433f9c625 upstream.
destroy() will decrement the refcount on the interface, so that
it needs to be taken so early that it never undercounts.
Fixes: 7fb57a019f94e ("USB: cdc-acm: Fix potential deadlock (lockdep warning)")
