[PATCH] virt: fsl_hypervisor: use matching dev_id for shutdown IRQ

[Avi Weiss]

fsl_hypervisor_init() registers the shutdown doorbell IRQ with a NULL
cookie, but both the unload and allocation-failure paths pass dbisr
to free_irq(). The IRQ core cannot find the registered action and
leaves the handler installed.

Pass dbisr to request_irq() so both cleanup paths remove the action.
