libnvdimm, pmem: use nvdimm_flush() for namespace I/O writes
nsio_rw_bytes() is used to write info block metadata to the namespace, so it should trigger a flush after every write. Replace wmb_pmem() with nvdimm_flush() in this path. Cc: Ross Zwisler <ross.zwisler@linux.intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
