SGX: UDD: Fix crash when cloning with FB sysfs entries
When a 3D app is runnning (avoiding the tearing effect) there
is a very high chance the pointer to the display is null just
after it has been extracted from the framebuffer and the UI is
cloned using the sysfs entries from the framebuffer.
This problem can be fixed by locking the framebuffer when the
synchronization is happening and also when the frame is being
pushed to the display as well.
