libertas_tf: Fix a bunch of function doc formatting issues

Kerneldoc expects attributes/parameters to be in '@*.: ' format and
gets confused if the variable does not follow the type/attribute
definitions.

Also demote one stray non-kernel-doc header.

Fixes the following W=1 kernel build warning(s):
