[PATCH 2/5] hisi_acc_vfio_pci: Fixes error return code issue

[Longfang Liu]

During the process of compatibility and matching of live migration
device information, if the isolation status of the two devices is
inconsistent, the live migration needs to be exited.

The current driver does not return the error code correctly and
needs to be fixed.
