net/smc: ignore loopback-ism when dumping SMC-D devices
Since loopback-ism is not a PCI device, the PCI information fed back by
smc_nl_handle_smcd_dev() does not apply to loopback-ism. So currently
ignore loopback-ism when dumping SMC-D devices. The netlink function of
loopback-ism will be refactored when SMC netlink interface is updated.
