handsfree-audio: Keep track whether defer_setup is enabled

'defer_setup' will be one of the inputs when enabling or disabling
support for wideband speech codecs, we will only enable wideband
speech support if the kernel supports deferred setup.

So, we have to have this information available, in this case it means
a global variable.
