rtsp-client: make closing more thread safe

Browse source 
+ Take the watch lock prior to using priv->watch
+ Flush both the watch and connection before closing / unreffing

gst_rtsp_connection_close() is not threadsafe on its own, this is
a workaround at the client level, where we control both the watch
and the connection
