Subject: [PATCH] uru4000: Call irq stop handler immediately if the transfer is
 cancelled

The irq handler may already be stopped if stop_irq_handler is called. In
that case, we should immediately call the handler rather than just never
calling it.

This fixes deactivation when the device is unexpectedly unplugged.

Closes: #355
