tipc: fix hanging clients using poll with EPOLLOUT flag
commit 517d7c79bdb398 ("tipc: fix hanging poll() for stream sockets")
introduced a regression for clients using non-blocking sockets.
After the commit, we send EPOLLOUT event to the client even in
TIPC_CONNECTING state. This causes the subsequent send() to fail
with ENOTCONN, as the socket is still not in TIPC_ESTABLISHED state.
In this commit, we:
- improve the fix for hanging poll() by replacing sk_data_ready()
with sk_state_change() to wake up all clients.
- revert the faulty updates introduced by commit 517d7c79bdb398
("tipc: fix hanging poll() for stream sockets").
