kselftest/alsa - mixer: Always log control names

Currently we only log the names of controls on error but it can be useful
to know what control we're testing (for example, when looking at why the
tests are taking a while to run). People looking at test logs may not have
direct access to the target system. This will increase the amount we write
to the console, hopefully that's buffered.
