ofp-parse: Don't segfault when an OpenFlow action's argument is missing.

Some actions checked that 'arg' was nonnull before attempting to parse it
but a lot of them didn't.  This commit avoids the segfault by substituting
an empty string when no argument is given.  It also updates a few of the
action implementations to correspond.
