nata - properly teardown interrupts on ENXIO
* When a ata controller cannot be attached (e.g. due to AHCI having
already taken its resources) be sure to teardown and release any
resources that had been obtained.
* This fixes a panic on certain motherboards (e.g. gigabyte / phenomX6)
where the ata controller ENXIO'd but left interrupt handlers setup.
An interrupt would then occur, access stale memory, and blow the machine
up.
