drm/amd/display: Free gamma after calculating legacy transfer function

Browse source 
[ Upstream commit 0e3a7c2ec93b15f43a2653e52e9608484391aeaf ]

[Why]
We're leaking memory by not freeing the gamma used to calculate the
transfer function for legacy gamma.

[How]
Release the gamma after we're done with it.
