[PATCH] ASoC: ops: Fix multiple value control type

[Sameer Pujar]

The commit aa2a4b897132("ASoC: ops: Fix boolean/integer detection for
simple controls") fixes false positives with controls not ending in
" Volume" string. But it now forces boolean type for the multi value
controls. Fix this by adding a max check before assigning types.

This fixes the second regression we noticed today, with mixer values
such as:

numid=5,iface=MIXER,name='PGA4.0 4 Master Capture Volume'
  ; type=BOOLEAN,access=rw---R--,values=2
  : values=on,on
  | dBscale-min=-50.00dB,step=1.00dB,mute=1

This caused an across-the-board fail with alsa-bat tests

Thanks Sameer!

Thanks but someone already sent a fix for this.
