Node Devices: Fix nodedev-list for fc_host & vports.

Node Devices: Fix nodedev-list for fc_host & vports.

In a system with Fiber Channel Host Adapters, a query to list all Fibre Channel
HBAs OR Vports currently returns empty list:
  $ virsh nodedev-list --cap fc_host

  $

Libvirt correctly discovers properties for all HBAs. However, the reporting
fails because of incorrect flag comparison while filtering these types.

This is fixed by removing references to 'VIR_CONNECT_LIST_NODE_DEVICES_CAP_*'
for comparison and replacing those with 'VIR_NODE_DEV_CAP_*'
