 join on same multicast-group dont return EINVAL

Dave,
        Do you have an opinion on this one? Linux code (for many years 
now)
allows you to do SSM calls after an ordinary ASM join, and vice-versa. The 
bugzilla
basically wants to see mixing the calls return EINVAL.
        That's not so hard to do, but if existing apps are mixing them, 
they, of
course, will fail. That's the intent of the RFC, but the code predates it 
and
happily converts between ASM and SSM automatically.
        So, I'm guessing the answer is "will not fix," but
it's your call. If you think we want to enforce this, I'll do
a patch.
