vfio: allow cpr-reboot migration if suspended
Allow cpr-reboot for vfio if the guest is in the suspended runstate. The
guest drivers' suspend methods flush outstanding requests and re-initialize
the devices, and thus there is no device state to save and restore. The
user is responsible for suspending the guest before initiating cpr, such as
by issuing guest-suspend-ram to the qemu guest agent.
Relax the vfio blocker so it does not apply to cpr, and add a notifier that
verifies the guest is suspended.
