I think that is the way to go.  Long time back the spl moved from

To fix every protocol individually makes not much sense.  We need
the lock in the socket layer, otherwise all the assertions cannot
work.  It would be difficult if we run the socket code with more
or less locks depending on the socket type.

I would say move most the splsoftnet() into uipc_socket.c and replace
it with an propper rwlock/mutex/whatever later.
