ALSA: control: remove useless assignment in .info callback of PCM chmap element
Control elements for PCM chmap return information to userspace abount the maximum number of available PCM channels as the number of values in the element. In current implementation the number is once initialized to zero, then assigned to. This is useless and this commit fixes it.
