tipc: Allow connect() to wait indefinitely
Cause a socket whose TIPC_CONN_TIMEOUT option is zero to wait indefinitely for a response to a connection request using connect(). Previously, specifying a timeout of 0 ms resulted in an immediate timeout, which was inconsistent with the behavior specified by Posix for a socket's receive and send timeout.
