pcm: direct: Move slave PCM state checks into XRUN check helper

Browse source 
The check of slave PCM state is always done before the client's
recoveries count check, so let's merge them to the common helper.
Also rename the helper function to snd_pcm_direct_check_xrun() as it's
checking both slave and client states now.
