CVE-2026-46074

spi: ch341: fix memory leaks on probe failures

In the Linux kernel, the following vulnerability has been resolved:

spi: ch341: fix memory leaks on probe failures

Make sure to deregister the controller, disable pins, and kill and free
the RX URB on probe failures to mirror disconnect and avoid memory
leaks and use-after-free.

Also add an explicit URB kill on disconnect for symmetry (even if that
is not strictly required as USB core would have stopped it in the
current setup).
