USB: Prepare for refactoring by adding extra udev checks.
commit 2d4fa940f99663c82ba55b2244638833b388e4e2 upstream.
The next patch will refactor the hub port code to rip out the recursive
call to hub_port_reset on a failed hot reset. In preparation for that,
make sure all code paths can deal with being called with a NULL udev.
The usb_device will not be valid if warm reset was issued because a port
transitioned to the Inactive or Compliance Mode on a device connect.
This patch should have no effect on current behavior.
