hisi_acc_vfio_pci: resolve duplicate migration states

Browse source

[ Upstream commit 8c6ac1730a ]

In special scenarios involving duplicate migrations, after the
first migration is completed, if the original VF device is used
again and then migrated to another destination, the state indicating
data migration completion for the VF device is not reset.
This results in the second migration to the destination being skipped
without performing data migration.
After the modification, it ensures that a complete data migration
is performed after the subsequent migration.
