drm/tilcdc: fix double kfree
commit c9a3ad25eddfdb898114a9d73cdb4c3472d9dfca upstream.
display_timings_release calls kfree on the display_timings object passed
to it. Calling kfree after it is wrong. SLUB debug showed the following
warning:
=============================================================================
BUG kmalloc-64 (Tainted: G W ): Object already free
