commit e96bca7eaa5747633ec638b065630ff83728982a upstream.
Slimbus streams are first prepared and then enabled, so the cleanup path
should reverse it. The unprepare sets stream->num_ports to 0 and frees
the stream->ports. Calling disable after unprepare was not really
effective (channels was not deactivated) and could lead to further
issues due to making transfers on unprepared stream.
