Yes, dark matter has mass, this is its defining characteristic: it seems to be a detectable mass, just doesn't interact electromagnetically. In any case, it's important to note the Schwarzchild model is a spherically symmetrical ball. Mass in our Universe seems more or less uniformly dispersed (with some anisotropy). Without a center for mass to collapse, I suspect the black hole dynamics don't apply.
