Declare msi_node with __free(device_node) and drop the out_put_node
label and its goto: the scoped cleanup puts the MSI controller node on
every return, as the label did.

No functional change intended.

Notes:
    Changes since v1:
    - Declare msi_node immediately before of_msi_xlate() rather than at the
      top of the function (Jonathan).
    - Kept Marek's Reviewed-by, since the generated code is unchanged.
