We need to save the current cursor location so that

drm/amd/display: Fix color module crash when hotplug monitors.
Assume we have two monitors, and monitor 0 is unplugged.
This shifts the internal state of index 1 to index 0 by memcpy.
This means there are two copies of the gamma pointer previously

When hotplug occurs, this re-assigns the new display with state[1],
which has some garbage left over from before, including the
gamma pointer.
We should correctly clear unused states and re-initialize correctly.
Also, due to async nature of the hotplug and other events like commit,
we also need to safe guard against sink that has been removed.
