[ Upstream commit 19abcd790b51b26d775e1170ba2ac086823cceeb ]
commit bd22885aa188 ("PCI: cadence: Refactor driver to use as a core library") while refactoring the Cadence PCIe driver to be used as library, removed pm_runtime_get_sync() from cdns_pcie_ep_setup() and cdns_pcie_host_setup() but missed to remove the corresponding pm_runtime_put_sync() in the error path. Fix it here.
