[PATCH] drm/bridge: nwl-dsi: Fix PM disable depth imbalance in nwl_dsi_probe

[Miaoqian Lin]

The pm_runtime_enable will increase power disable depth.
Thus a pairing decrement is needed on the error handling
path to keep it balanced according to context.

Fixes: 44cfc62 ("drm/bridge: Add NWL MIPI DSI host controller support")
