[PATCH 2/9] libnvdimm, pfn: clean up pfn create parameters

[Dan Williams]

In all cases __nd_pfn_create is called with default parameters which are
then overridden by values in the info block.  Clean up pfn creation by
dropping the parameters and setting default values internal to
__nd_pfn_create.
