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.
