Fix KASSERT(solocked(sb->sb_so)) failure in sbappendaddr that is called
eventually from key_sendup_mbuf
If key_sendup_mbuf isn't passed a socket, the assertion fails.
Originally in this case sb->sb_so was softnet_lock and callers
held softnet_lock so the assertion was magically satisfied.
Now sb->sb_so is key_so_mtx and also softnet_lock isn't always
held by callers so the assertion can fail.
Fix it by holding key_so_mtx if key_sendup_mbuf isn't passed a socket.
