A snd_pcm_status() call for the direct plugins receives the status from the slave PCM, but this doesn't contain a valid appl_ptr, since the slave PCM for the direct plugins is in a free-wheel mode, hence the appl_ptr is always zero. This result in the inconsistent status->appl_ptr and pcm->appl.ptr, hitting the recently introduced assert() call.
Fix it by transferring the plugin's appl_ptr to the upper caller.
