rGcc86794b0319: gpiobus: plug IRQ leaks
Summary

Unmap the IRQ instead of just freeing the map data in the case of an
error. Also don't overwrite the resource's virtual address since the
copy of the map data made by intr_activate_irq is stored there.

Implement gpiobus_release_resource so it can unmap IRQs mapped by
gpio_alloc_intr_resource.
