Subject: libnvdimm, namespace: remove redundant initialization of 'nd_mapping'
Git-commit: 59858d3d54cfad1f8db67c2c07e4dd33bb6ed955
Patch-mainline: v4.16-rc1
References: FATE#326060

instead it is being updated to a new value in all the cases where it
is being read afterwards, hence the initialization is redundant and
can be removed.

Cleans up clang warning:
drivers/nvdimm/namespace_devs.c:2411:21: warning: Value stored to
'nd_mapping' during its initialization is never rea
