qcacld-3.0: Remove unnecessary includes from ol_if_athvar.h

The header file ol_if_athvar.h is strange in that it is a qcacld-3.0
file that is included by files in the qca-wifi-host-cmn project.  That
model does not conform to the software architecture so there is a plan
to correctly refactor the file. As a preliminary step remove all
include directives that are not actually required by the files that
include this header file.
