soundwire: stream: Add missing clear of alloc_slave_rt

[ Upstream commit 58d95889f3c2064c6139ee94bb0e4d86e1ad4eab ]

The current path that skips allocating the slave runtime does not clear
the alloc_slave_rt flag, this is clearly incorrect. Add the missing
clear, so the runtime won't be erroneously cleaned up.
