pmem: fix a name collision

Kernel test robot detected name collision when compiled on 'um'
architecture.  Rename "to_phys()"  to "pmem_to_phys()".

>> drivers/nvdimm/pmem.c:48:20: error: conflicting types for 'to_phys'; have 'phys_addr_t(struct pmem_device *, phys_addr_t)' {aka 'long long unsigned int(struct pmem_device *, long long unsigned int)'}
