Subject: [PATCH] drm/radeon/ni_dpm: remove redundant NULL check
'leakage_table' will always be successfully initialized as a pointer
to '&rdev->pm.dpm.dyn_state.cac_leakage_table'.
Remove unnecessary check if only to silence static checkers.
Found by Linux Verification Center (linuxtesting.org) with static
analysis tool Svace.
Fixes: 69e0b57a91ad ("drm/radeon/kms: add dpm support for cayman (v5)")
