tipc: fix possible crash in __tipc_nl_net_set()
syzbot reported a crash in __tipc_nl_net_set() caused by NULL dereference.
We need to check that both TIPC_NLA_NET_NODEID and TIPC_NLA_NET_NODEID_W1
are present.
We also need to make sure userland provided u64 attributes.
Fixes: d50ccc2d3909 ("tipc: add 128-bit node identifier")
