libnvdimm: Fix nvdimm_probe error on NVDIMM-N
'ndctl list --buses --dimms' does not list any NVDIMM-Ns since
they are considered as idle. ndctl checks if any driver is
attached to nmem device. nvdimm_probe() always fails in
nvdimm_init_nsarea() since NVDIMM-Ns do not implement optinal
ND_CMD_GET_CONFIG_DATA command.
Change nvdimm_probe() to accept the case that the CONFIG_DATA
command is not implemented for NVDIMM-Ns. The driver attaches
without ndd, which keeps it no-op to the device.
