avformat/rtsp: initialize reply1

It seems reply1 is initialized by ff_rtsp_send_cmd() in most cases but there
are code paths like "continue" which look like they could skip it but even if not
writing this so a complex loop after several layers of calls initialized a local
variable through a pointer is just bad design.
This patch simply initialized the variable.

Fixes: CID1473532 Uninitialized scalar variable
