drm/xe: Use migrate engine for page fault binds

Browse source

We must use migrate engine for page fault binds in order to avoid a
deadlock as the migrate engine has a reserved BCS instance which cannot
be stuck on a fault. To use the migrate engine the engine argument to
xe_migrate_update_pgtables must be NULL, this was incorrectly wired up
so vm->eng[tile_id] was always being used. Fix this.
