Subject: nouveau: remove a few function stubs
Git-commit: 107ba59fc6d761ca996243dd0a1ee89addc295af
Patch-mainline: v5.4-rc1
References: jsc#SLE-16387, bsc#1152489

nouveau_dmem_migrate_vma and nouveau_dmem_convert_pfn are only called
when CONFIG_DRM_NOUVEAU_SVM is enabled, so there is no need to provide
!CONFIG_DRM_NOUVEAU_SVM stubs for them.
