Volume: Code cleanup for minimum gain value limiting 

This patch changes the condition for limiting the smallest gain to
eliminate a never executed code part when VOL_MIN is defined as zero. The
variable v is unsigned integer so less than zero is not possible.
The functionality is not modified by this patch.
