changed snd_pcm_close() behaviour

changed snd_pcm_close() behaviour

[Jaroslav Kysela]

Hi all,

	after discussion with Takashi and others on this list, the 
behaviour of snd_pcm_close() function has been changed in this way:

The stream is stoped and all samples (if any) are droped. It means, that
if the user space code wants to flush samples to output, the
snd_pcm_drain() function must be called before the snd_pcm_close() call.

	I hope that this change doesn't cause any problems in any 
application. Anyway, please, report all problems.
