ALSA: hdspm: Fix zero-division

[ Upstream commit c1099c3294c2344110085a38c50e478a5992b368 ]

HDSPM driver contains a code issuing zero-division potentially in
system sample rate ctl code.  This patch fixes it by not processing
a zero or invalid rate value as a divisor, as well as excluding the
invalid value to be passed via the given ctl element.
