ofp-msgs: Fix definitions of OF1.4 OFPT_GET_ASYNC_REPLY and OFPT_SET_ASYNC.
The structures declared in ofp-msgs.h for messages definitions should not
include an OpenFlow header (its presence is implied), but the definition of
these messages did. This commit fixes the definitions.
The visible bug was really minor here: messages of these kinds without any
TLVs would be rejected by the OpenFlow parser. But OVS never sends these
messages without TLVs, so probably no one ever noticed this. (Also, the
OVS support for OF1.4 is still incomplete and experimental.)
