Rework setting the AVIRT map, and stream creation

To ensure that a stream is able to change it's mapping (before card is sealed), we cannot create the stream PCM upon setting the mapping. This had to be reworked to allow multiple setting of the mapping if so required.

The PCM ops table for a given stream is now allocated and stored in the snd_avirt_stream struct, to allow retrieval and manipulation upon mapping change.
