Mathieu Malaterre 9cbaf4d969 video: offb: Deallocate the color map 
The function offb_destroy did not deallocate the color map leaving some
memory around after destruction. Call the color map deallocate function to
remove the memory leak.

Handle another case where color map should have been deallocated during an
error code path.

Fix memory leaks reported by kmemleak:
