Provide workaround for a bug in pcm driver introduced with format emulation

changes.

At present newpcm has sticky parameter settings, even when an
inappropriate value is set.  For instance, set format to alaw on h/w
that does not support alaw; newpcm interface state records format as
alaw, and subsequent unrelated state changes may fail, ie a rate change.

In mpg123 this can cause files to be played at lower quality
than available because of mis-diagnosis of available formats and
sample rates.  E.g downsamples everything to 11025Hz on this h/w as
12kHz probing breaks state and subsequent probes for higher supported
sampling rates.
