Currently the ospf6d's commands with non-exist vrfs can't give the error

This commit adds a macro "OSPF6_CMD_CHECK_VRF" to give error information
if with non-exist vrfs. As usual, skip the checking process in the case
of json.

So one command can call this macro to do the checking process in its
end. At that time it need know json style or not, so add "json" parameter for
several related functions.

BTW, suppress the build warning of the macro `OSPF6_FIND_VRF_ARGS`:
"Macros starting with if should be enclosed by a do - while loop to avoid
