util: skip RDMA detection for non-PCI network devices
Only PCI devices have '/sys/class/net/<ifname>/device/resource' so we
need to skip this check for all other network devices.
Without this patch and RDMA enabled libvirt will not detect any network
device that doesn't have the path above which includes 'lo', 'virbr',
'tun', etc.
