drm/amdgpu/pm: fix ref count leak when pm_runtime_get_sync fails

[ Upstream commit 66429300e1bd9cdfbe96cfc475e4964db2a36921 ]

The call to pm_runtime_get_sync increments the counter even in case of
failure, leading to incorrect ref count.
In case of failure, decrement the ref count before returning.
