[PATCH] docs: ABI: sysfs-bus-nvdimm: fix unexpected indentation error

[David Reaver]

Fix the following error when running make htmldocs:

Documentation/ABI/testing/sysfs-bus-nvdimm:10: ERROR: Unexpected indentation.

This is caused by missing newlines before the code examples. In particular,
before this patch, the second example for ctl_res_cnt doesn't render properly.
