Yi Yang 12433c87d2 nvdimm: rectify the illogical code within nd_dax_probe() 
[ Upstream commit b613521014 ]

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.
