tipc: fix modprobe tipc failed after switch order of device registration
[ Upstream commit 532b0f7ece4cb2ffd24dc723ddf55242d1188e5e ]
Error message printed:
modprobe: ERROR: could not insert 'tipc': Address family not
supported by protocol.
when modprobe tipc after the following patch: switch order of
device registration, commit 7e27e8d6130c
("tipc: switch order of device registration to fix a crash")
Because sock_create_kern(net, AF_TIPC, ...) is called by
tipc_topsrv_create_listener() in the initialization process
of tipc_net_ops, tipc_socket_init() must be execute before that.
I move tipc_socket_init() into function tipc_init_net().
Fixes: 7e27e8d6130c
