Subject[PATCH] selftests: alsa: Better error messages
From
This allows for potentially better machine-parsing due to an
expected / fixed format. Also because of eyecandy reasons.

Whenever possible, errors will start with the name of the
offending card/control, separated by the error with colons.

Whenever there is a description of an error given, the generated
error string from snd_strerror will be (mostly) enclosed in
parentheses at the end.

Clarity of error messages have been (hopefully) improved.
