in-band: Avoid "cast increases required alignment of target type" warning.

Casting a struct ofp_action_output object's address to type union
ofp_action * provokes a warning on sparc.  It's easier to just declare
the object as having type union ofp_action, even though I don't think that
there is a real problem here.
