After the previous patch this flag will check always clear, as it's
never set for shmem backed and userptr objects, so we can remove it.

[danvet: Yeah this isn't really fixes but it's a nice cleanup to
clarify the code but not really worth the hassle of backmerging. So
just add to -fixes, we're still early in -rc.]
