Subject: Eliminated 'unused variable' compiler warning generated with -DLWS_WITH_NO_L...

The unused variable was only declared for use in a log macro that's
compiled out with the above compiler switch. I removed the declaration
and casted the variable at each use in the block.

AG: convert to void case reference irrespective of logging enabled.
AG: travis.yml: add -DLWS_WITH_NO_LOGS=ON that also enables lwsws + cgi code
