[PATCH] docs: ABI: sysfs-bus-nvdimm: correct indentations

[Hu Haowen]

The identations from line 1 to 4 within sysfs-bus-nvdimm were wrongly
incompatible with the indentations of the following contents. Hence
correct them.

Discovered when I was executing "make htmldocs" and received the
following stderr output:

    /<... root dir ...>/Documentation/ABI/testing/sysfs-bus-nvdimm:11: WARNING: Unexpected indentation.
