In qcom_probe_nand_devices() function, the error code returned by qcom_nand_host_init_and_register() is converted to -ENODEV in the case of failure. This poses issue if -EPROBE_DEFER is returned when the dependency is not available for a component like parser. So let's restructure the error handling logic a bit and return the actual error code in case of qcom_nand_host_init_and_register() failure.
