neutron: pci_request logic considers 'direct-physical' vnic type

Browse Source 
Since the following change:

If1ab969c2002c649a3d51635ca2765c262e2d37f

Neutron supports this vnic type, which ties in with the work that
enabled PF passthrough.

This patch makes sure to properly translate the 'direct-physical'
vnic-type port from Neutron to a request for a PF.
