drm/amd/display: fix a bug to dereference already freed old current state memory
[why]
During minimal transition commit, the base state could be freed if it is current state.
This is because after committing minimal transition state, the current state will be
swapped to the minimal transition state and the old current state will be released.
the release could cause the old current state's memory to be freed. However dc
will derefernce this memory when release minimal transition state. Therefore, we
need to retain the old current state until we release minimal transition state.
