drm/xe/migrate: Allow xe_migrate_vram() also on non-pagefault capable devices 



The drm_pagemap functionality does not depend on the device having
recoverable pagefaults available. So allow xe_migrate_vram() also for
such devices. Even if this will have little use in practice, it's
beneficial for testin multi-device SVM, since a memory provider could
be a non-pagefault capable gpu.
