[PATCH -next] Documentation: cpu-idle-cooling: fix a SEVERE docs build failure

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

Sphinx ('make htmldocs') stops with a SEVERE error:


Sphinx parallel build error:
SystemMessage: /home/rdunlap/lnx/next/linux-next-20200120/Documentation/driver-api/thermal/cpu-idle-cooling.rst:69: (SEVERE/4) Unexpected section title.

^
|

so fix the .rst file so that the SEVERE build error does not happen.
Also fix another minor formatting warning (unexpected unindent).
