Subject: libnvdimm: remove redundant assignment to pointer 'dev'
Git-commit: 0cbfeef230571b132d2ac2ea4346b200b311258f
Patch-mainline: v4.16-rc7
References: FATE#326060

Pointer dev is being assigned a value that is never read, it is being
re-assigned the same value later on, hence the initialization is redundant
and can be removed.

Cleans up clang warning:
drivers/nvdimm/pfn_devs.c:307:17: warning: Value stored to 'dev' during
its initialization is never read
