wm4 dac5b598f5 chmap_sel: prefer inexact equivalents over perfect upmix
Given 5.1(side), this lets it pick 5.1 from [5.1, 7.1]. Which was
probably the original intention of this replacement stuff. Until now,
the opposite was done in some cases.

Keep the old heuristic if the replacement is not perfect. This would
mean that a subset of the channel layout is an inexact equivalent, but
not all of it.

(My conclusion is that audio output APIs should be designed to simply
take any channel layout, like the PulseAudio API does.)
