pcm: improve handling for snd_pcm_wait()
The snd_pcm_wait() function is called also internally from
the various plugins to wait for the drain with -1 and from i/o
routines in pcm.c.
Define two special negative timeout values to distinguish the
drain and i/o wait and calculate the maximal timeout according
the wait place.
