So far, our implementation of WARN_ON() cannot be used in the following
situation:

if ( WARN_ON() )
     ...

This is because the WARN_ON() doesn't return whether a warning. Such

... warning has been triggered.

construction can be handy to have if you have to print more information
and now the stack track.

Rework the WARN_ON() implementation to return whether a warning was
triggered. The idea was borrowed from Linux.
