[PATCH v5 01/10] hw/audio/virtio-sound: remove channel positions field from VirtIOSoundPCMStream

[Alexander Mikhalitsyn <alexander@mihalicyn.com>]

From: Alexander Mikhalitsyn <aleksandr.mikhalitsyn@futurfusion.io>

This field seems to be useless currently, as we
don't implement VIRTIO_SND_R_CHMAP_INFO.
