drm/tegra: dpaux: Fix PM disable depth imbalance in tegra_dpaux_probe

Browse source

The pm_runtime_enable function increases the power disable depth,
which means that we must perform a matching decrement on the error
handling path to maintain balance within the given context.
Additionally, we need to address the same issue for pm_runtime_get_sync.
We fix this by invoking pm_runtime_disable and pm_runtime_put_sync
when error returns.
