[PATCH] gpu: host1x: mipi: Fix device_node reference leak in tegra_mipi_request()

[Felix Gu]

In tegra_mipi_request(), when provider.np is not equal with args.np, it
returns without calling of_node_put(args.np), causing a reference leak.

Convert to use the existing goto out pattern to ensure proper cleanup.
