media: omap3isp: Prevent enabling CCDC when stopping streaming

Browse Source 
Commit ... prevented restarting CCDC through its interrupt handler when
it's about to be disabled. It missed to address the case when CCDC might
be enabled due to queueing a buffer. Do that now.

Fixes: dd12ed17ce ("omap3isp: Don't restart CCDC if we're about to stop")
