v4l2: v4l2_compat_manager: Don't print "camera not found" on openat()

Browse source 
Some applications (like Firefox) run open() many times on video device
nodes. This may lead to user confusion when they see "INFO V4L2Compat
v4l2_compat_manager.cpp:146 No camera found for /dev/videoX" over and
over again.

Lower the log level to debug so that we can still get this information
on debug, and so users won't see it all the time.
