media: siano: fix memory leak of debugfs members in smsdvb_hotplug

Browse Source 
[ 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.
