1. The logging macros implicitly takes care of embedding function name
in the log, hence there is no need to include __func__ again.
Getting rid of redundant __func__ reduces driver memory footprint.
2. Instead of adding __func__ to the qdf_nofl_* macros, its better to use
qdf_* which already takes care of adding __func__.
