Right now, only static dax regions have a valid @pgmap pointer in its
struct dev_dax. Dynamic dax case however, do not.

In preparation for device-dax compound pagemap support, make sure that
dev_dax pgmap field is set after it has been allocated and initialized.

I think this is ok to fold into the patch that needs it.

OK, I've squashed that in.
