Other drivers fail resource allocation when a list
of modifiers for the resource is provided but none
are supported. This includes cases when the never-
supported DRM_FORMAT_MOD_INVALID modifier is
explicitly passed. To enable matching that
functionality in nouveau, use an empty modifier
list rather than creating a one-entry list
containing only DRM_FORMAT_MOD_INVALID when the
non-modifier resource creation function is used.
This change stops short of failing allocations
when no modifier is specified, because the current
code ignores all modifiers except the linear
modifier when creating resources, so there is not
yet a framework in place to determine which
modifiers are valid for a given resource creation
request, and hence no way to reject only those
which are invalid.
