Suggested correction

The macro GST_RTSP_CHECK() is called before any context is pushed, and this
calls gst_rtsp_connection_accept() which can sometimes fail e.g. in the case of
an nmap port scan. 

In our implementation this ends up logging a critical in the system log when
gst_rtsp_context_pop_current() tried to pop a non-existent context.
