[PATCH] drm/amd/powerplay: fix memory leak on tdp_table

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

tdp_table is being leaked on an error exit return path,
fix this by kfree'ing it.  Also swap comparison around to make the
patch warning free with checkpatch.

Leak found via static analysis with CoverityScan
