media: mc: mark the media devnode as registered from the, start
commit 4bc60736154bc9e0e39d3b88918f5d3762ebe5e0 upstream.
First the media device node was created, and if successful it was
marked as 'registered'. This leaves a small race condition where
an application can open the device node and get an error back
because the 'registered' flag was not yet set.
Change the order: first set the 'registered' flag, then actually
register the media device node. If that fails, then clear the flag.
