usbnet: Use atomic_load/store_relaxed for unp_dying.

This way we don't need to hold the core lock to avoid upsetting
sanitizers (which probably find the current code upsetting), and we
can use it to exit early from timeout loops that run under the core
lock (which is probably not necessary for them to do anyway, but
let's worry about that later).
