dmaengine: ste_dma40: Fix probe IRQ leak
d40_probe() registers the hardware interrupt before several later probe
steps that can fail. Those error paths jump to destroy_cache without
freeing the IRQ, leaving the handler registered after probe resources have
been released.
Route failures after a successful IRQ request through a dedicated cleanup
label. Keep the request before DMAengine registration because that
registration publishes channels to clients.
