[PATCH V2 4/6] cpr: relax vhost migration blockers

vhost blocks migration if logging is not supported to track dirty memory, and vhost-user blocks it if the log cannot be saved to a shm fd. vhost-vdpa blocks migration if both hosts do not support all the device's features using a shadow VQ, for tracking requests and dirty memory. vhost-scsi
