Let's hot plug an adapter, domain or control domain into the guest when it is assigned to a matrix mdev that is attached to a KVM guest. Likewise, let's hot unplug an adapter, domain or control domain from the guest when it is unassigned from a matrix_mdev that is attached to a KVM guest. Whenever an assignment or unassignment of an adapter, domain or control domain is performed, the APQNs and control domains assigned to the matrix mdev will be filtered and assigned to the AP control block (APCB) that supplies the AP configuration to the guest so that no adapter, domain or control domain that is not in the host's AP configuration nor any APQN that does not reference a queue device bound to the vfio_ap device driver is assigned. After updating the APCB, if the mdev is in use by a KVM guest, it is hot plugged into the guest to dynamically provide access to the adapters, domains and control domains provided via the newly refreshed APCB.
