media: platform: sti: hva: Fix runtime PM imbalance on error
[ Upstream commit d912a1d9e9afe69c6066c1ceb6bfc09063074075 ]
pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code. Thus a pairing decrement is needed on
the error handling path to keep the counter balanced.
