ofp-util: Make ofputil_encode_set_protocol() able to return failure.
Soon, it's not going to be possible to switch between every possible
protocol on an established OpenFlow connection, yet
ofputil_encode_set_protocol() didn't have a documented way to report such
a problem. This commit adds a means for reporting and makes its callers
able to handle the problem.
Also, initially make ofputil_encode_set_protocol() fail when the current
and requested protocols are for different OpenFlow versions.
