This is the only reason theres a need to specify lwmutex_sq id at creation. unlike sys_cond, lwcond isn't connected to lwmutex at the lv2 level. SYS_SYNC_RETRY fix is done explicitly at the firmware level. This fixes issues when the original lwcond and lwmutexol data got corrupted or deallocated, this can happen when the program simply memcpy the control data to somewhere else. Or if it uses direct lv2 the lwcond conrol param can even be NULL which will make it access violate when dereferncing it. (This param is unchecked and can be anything)
