[ovs-dev] [ofp-util logging 1/3] ofp-util: Improve log message for bad OpenFlow action length.

[Ben Pfaff]

First, this is an important message since it indicates a bug in the
controller, so log it at warning level instead of debug level--we want to
know about it.

Second, properly byteswap the action type.

Third, use the correct PRIu16 format specified for a uint16_t.
