[PATCH] conf: Remove left justification for SND_CONFIG_TYPE_REAL

[Simon Christensson]

In order to avoid extra padding replace data type "%-16g" (left justification) with default right justification "%16g" when printing snd_config type SND_CONFIG_TYPE_REAL.


Example for control "min_dB" available in softvol:

Before patch: "min_dB -50             "

After patch: "min_dB -50.0"
