[media] v4l: Correct definition of v4l2_buffer.flags related to cache management
V4L2_BUF_FLAG_NO_CACHE_INVALIDATE and V4L2_BUF_FLAG_NO_CACHE_CLEAN were define incorrectly in the documentation. Fix this by changing the documentation to match reality. Signed-off-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
