For completion context, the first src mbuf 'userdata' field
is filled in. The wrong index was being used to set this which
would never cause a problem because only the first src mbuf is
used. Also when an extra src mbuf is added we weren't setting
userdata which again isn't a real problem but for consistency
I'd like to set it since all other src mbufs have it set.
