sound: pcm_lib: fix unsorted list constraint handling
commit b1ddaf681e362ed453182ddee1699d7487069a16 upstream.
snd_interval_list() expected a sorted list but did not document this, so
there are drivers that give it an unsorted list. To fix this, change
the algorithm to work with any list.
This fixes the "Slave PCM not usable" error with USB devices that have
multiple alternate settings with sample rates in decreasing order, such
as the Philips Askey VC010 WebCam.
