meta-flow: Use correct OF1.2+ errors for invalid fields in actions.

OFPERR_OFPBAC_BAD_ARGUMENT is not as specific as the errors provided by
OpenFlow 1.2 and later.

Some of these errors needed Nicira extension numbers for use with OpenFlow
1.0 and 1.1, so this commit also adds those.

Some of these errors had poor explanations likely to confuse users, so this
commits improves them.

Some of the errors had the wrong names, so this commit fixes them.
