[PATCH] PCI: rcar: Fix runtime PM imbalance in rcar_pcie_ep_probe

[Dinghao Liu]

pm_runtime_get_sync() will increase the runtime PM counter
even it returns an error. Thus a pairing decrement is needed
to prevent refcount leak. Fix this by replacing this API with
pm_runtime_resume_and_get(), which will not change the runtime
PM counter on error.
