PCI: cadence: Fix DMA range mapping early return error

Function cdns_pcie_host_map_dma_ranges() iterates over a PCIe host bridge
DMA ranges using the resource_list_for_each_entry() iterator, returning an
error if cdns_pcie_host_bar_config() fails.

49e427e6 ("Merge branch 'pci/host-probe-refactor'") botched a merge so
it *always* returned after the first DMA range, even if no error occurred.

Fix the error checking so we return early only when an error occurs.
