nvdimm/pmem: Treat alloc_dax() -EOPNOTSUPP failure as non-fatal
In preparation for checking whether the architecture has data cache
aliasing within alloc_dax(), modify the error handling of nvdimm/pmem
pmem_attach_disk() to treat alloc_dax() -EOPNOTSUPP failure as non-fatal.
[ Based on commit "nvdimm/pmem: Fix leak on dax_add_host() failure". ]
