3f6ed59ec400a58646e766a323f7f8047f044b98 vfio/migration: Refactor vfio_save_state() return value
Currently, vfio_save_state() returns 1 regardless of whether there is
more data to send or not. This was done to prevent a fast changing VFIO
device from potentially blocking other devices from sending their data,
as qemu_savevm_state_iterate() serialized devices.
Now that qemu_savevm_state_iterate() no longer serializes devices, there
is no need for that.
Refactor vfio_save_state() to return 0 if more data is available and 1
if no more data is available.
