nvdimm: rectify the illogical code within nd_dax_probe()
[ Upstream commit b61352101470f8b68c98af674e187cfaa7c43504 ]
When nd_dax is NULL, nd_pfn is consequently NULL as well. Nevertheless,
it is inadvisable to perform pointer arithmetic or address-taking on a
NULL pointer.
Introduce the nd_dax_devinit() function to enhance the code's logic and
improve its readability.
