pulse-server: fix channels property

Browse source 
Setting the channel property should create as many channels as
requested, not just the number from the default channel map.

If no channel_map is set, use the default one if the channels match
or use one with unknown channel layout otherwise.

Check the configured channels against the channel map and error
if there is a mismatch.
