[PATCH v7 03/14] PCI: rzg3s-host: Don't mix goto-based unwinding and cleanup helpers

[Claudiu Beznea <claudiu.beznea@kernel.org>]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

rzg3s_pcie_probe() releases the sysc_np OF node through the
__free(device_node) annotation, while the rest of the function uses
goto-based unwinding. According to cleanup.h, the two styles should
not be mixed within a function, as this makes the ownership semantics
hard to follow. Drop the annotation and call of_node_put() explicitly
on the exit paths instead.

Fixes: 7ef502fb35b2 ("PCI: Add Renesas RZ/G3S host controller driver")
