msm: gsi: allow start_xfer when channel is not running
GSI doorbell can be rang even if the channel is not running. The doorbell will be cached and will be applied when channel moves to running state. This change allow ringing the doorbell for channels before starting them to avoid a race condition between initial buffer replenish and channel start.
