Tools: Testbench: Avoid warning about fallthrough and fix return code 

The build of testbench fails at /* fallthrough */ with xt-clang
build for MTL since warnings are treated in tesbench build as
errors. The re-arrange of default and 'h' fixes also return
of -EINVAL in default case for unknown option.
