tipc: remove tsk->connected for connectionless sockets
Until now, for connectionless sockets the peer information during
connect is stored in tsk->peer and a connection state is set in
tsk->connected. This is redundant.
In this commit, for connectionless sockets we update:
- __tipc_sendmsg(), when the destination is NULL the peer existence
is determined by tsk->peer.family, instead of tsk->connected.
- tipc_connect(), remove set/unset of tsk->connected.
Hence tsk->connected is no longer used for connectionless sockets.
There is no functional change in this commit.
