libertas: use kernel-doc notation, fix comment style

Browse source 
Convert all libertas/ files to use kernel-doc notation instead
of whatever it was (doxygen?).

Add or fix function parameters in several places.

Use expected style for multi-line comments in lots of places.

Remove erroneous /** in multiple places.
