[ Upstream commit 8d6ccf5cebbc7ed1dee9986e36853a78dfb64084 ]
As part of sdw_stream_remove_master(), sdw_stream_remove_slave() is called
which results in bus lock being acquired twice.
So, fix it by performing specific Slave remove operations in
sdw_release_master_stream() instead of calling sdw_stream_remove_slave().
