vfio/migration: Make x-migration-multifd-transfer VFIO property mutable
DEFINE_PROP_ON_OFF_AUTO() property isn't runtime-mutable so using it would mean that the source VM would need to decide upfront at startup time whether it wants to do a multifd device state transfer at some point. Source VM can run for a long time before being migrated so it is desirable to have a fallback mechanism to the old way of transferring VFIO device state if it turns to be necessary. This brings this property to the same mutability level as ordinary migration parameters, which too can be adjusted at the run time. Signed-off-by: Maciej S.
