Andriy Gapon a5669965bd dsp/pcm: allow to mmap both read and write buffers using the same fd
This brings our implementation in line with OSS specification for
systems that support mmap.  The change should also improve compatibility
with OSS software not specifically written for FreeBSD, e.g. PulseAudio
OSS plugin.
