drm/xe/vf: Requeue recovery on GuC MIGRATION error during VF post-migration

Handle GuC response `XE_GUC_RESPONSE_VF_MIGRATED` as a special case in the
VF post-migration recovery flow. When this error occurs, it indicates that
a new migration was detected while the resource fixup process was still in
progress. Instead of failing immediately, requeue the VF into the recovery
path to allow proper handling of the new migration event.

This improves robustness of VF recovery in SR-IOV environments where
migrations can overlap with resource fixup steps.
