ASoC: dapm: Do not add un-muxed paths to MUX control
Paths that are directly connected to a MUX widget are not affected by
changes to the MUX's control. Rather than checking if a path is directly
connected each time the MUX is updated do it only once when MUX is created.
We can also remove the check for e->texts[mux] != NULL, since if that
condition was true the code would have had already crashed much earlier (And
generally speaking if a enum's 'texts' entry is NULL it's a bug in the
driver).
