[ Upstream commit abf287eeff4c6da6aa804bbd429dfd9d0dfb6ea7 ]
When dvb_create_media_graph fails, the debugfs kept inside client should
be released. However, the current implementation does not release them.
Fix this by adding a new goto label to call smsdvb_debugfs_release.
Fixes: 0d3ab8410dcb ("[media] dvb core: must check dvb_create_media_graph()")
