Code Issues Proposed changes

Reattach the PCI device to host driver

Browse Source 
This patch adds the ability to do a virsh nodedev-reattach of the
PCI device.   This detaches the PCI device from the pci-stub to it's
original host driver (lpfc) in the hope that it does a reset of the
device upon reattach.
