[PATCH] drm/amd/display: Fix memleak on input transfer function

[sunpeng.li at amd.com]

From: "Leo (Sunpeng) Li" <sunpeng.li at amd.com>

Input transfer function creation is now done when the plane is created.
This is done within the following change:

    Author: Anthony Koo <Anthony.Koo at amd.com>
        drm/amd/display: Have DC manage its own allocation of gamma

Therefore, we no longer need to create it when filling in the plane
attributes.
