[libvirt] [PATCH] pci: Log debug messages when manipulating the inactive list

[Andrea Bolognani]

Most of the changes to the list of active and inactive PCI devices
happen in virHostdev, where they are properly logged.

virPCIDeviceDetach() and virPCIDeviceReattach(), however, change the
inactive list as well, so they should be logging similar messages.
