Stream client: fix disconnection logic
Previously closing the client did not alter its state, so we might
end-up with a client without any file descriptors, but being in state
STREAM_CLI_STATE_CONNECTED. Fix this inconsistency by setting
appropriate state.
Related issue is that reconnect function, which is always (at least in
the library and examples) called when some problem with the connection
is detected, closed the connection only after checking whether
reconnection is enabled. This might result in another inconsistency
fixed in this patch by moving the check below connection cleanup.
While at it, also move connection close logging to appropriate place:
it's confusing to see logs about connection being closed while in
reality it wasn't even established.
