drm/amdgpu: fix a memory leak in amdgpu_ras_feature_enable
This patch fixes a memory leak in the amdgpu_ras_feature_enable() function.
The leak occurs when the function sends a command to the firmware to enable
or disable a RAS feature for a GFX block. If the command fails, the kfree()
function is not called to free the info memory.
Fixes: 9f051d6ff13f ("drm/amdgpu: Free ras cmd input buffer properly")
