[PATCH 15/19] soundwire: stream: move list addition to sdw_slave_alloc_rt()

From: Pierre-Louis Bossart <pierre-louis.bossart at linux.intel.com>
Simplify sdw_stream_add_slave() by moving the linked list management
inside of the sdw_slave_alloc_rt_free() helper, this also makes the
alloc/free helpers more symmetrical.
