fix pcm_set_params() documentation
fix pcm_set_params() documentation

The documentation for the latency parameter of pcm_set_params() says
that the value 0 uses an optimal value.  This is wrong, as there is no
special handling for 0, and the result will be a buffer of minimal size.
Therefore, remove that incorrect statement.
