The guest's AP configuration is cleared when the mdev is removed, so
userspace must be notified that the AP configuration has changed. To this
end, this patch:
* Removes call to 'signal_guest_ap_cfg_changed()' function from the
'vfio_ap_mdev_unset_kvm()' function because it has no affect given it is
called after the mdev fd is closed.
* Adds call to 'signal_guest_ap_cfg_changed()' function to the
'vfio_ap_mdev_request()' function to notify userspace that the guest's
AP configuration has changed before signaling the request to remove the
mdev.
Minor change - Fixed an indentation issue in function
'signal_guest_ap_cfg_changed()'
