s390x/pci: refresh fh before disabling aif
|
|
|
|
Typically we refresh the host fh during CLP enable, however it's possible
|
|
that the device goes through multiple reset events before the guest
|
|
performs another CLP enable. Let's handle this for now by refreshing the
|
|
host handle from vfio before disabling aif.
|
|
