drm/xe: Wait for migration job before unmapping pages
commit 5e0a67fdb894d34c5f109e969320eef9ddae7480 upstream.
Fix a potential GPU page fault during tt -> system moves by waiting for
migration jobs to complete before unmapping SG. This ensures that IOMMU
mappings are not prematurely torn down while a migration job is still in
progress.
