Subject: [PATCH][drm-next] drm/amd/powerplay: remove redundant duplicated return check

From: Colin Ian King <colin.king@...onical.com>

The check on ret is duplicated in two places, it is redundant code.
Remove it.

Addresses-Coverity: ("Logically dead code")
Fixes: b94afb61cdae ("drm/amd/powerplay: honor hw limit on fetching metrics data for navi10")
