ALSA: pcm - Tell user that stream to be rewound is suspended
Return STRPIPE instead of EBADF when userspace attempts to rewind of forward a stream that was suspended in meanwhile, so that it can be recovered by snd_pcm_recover(). This was causing Pulseaudio to unload the ALSA sink module under a race condition when it attempted to rewind the stream right after resume from suspend, before writing to the stream which would cause it to revive the stream otherwise. Tested to work with Pulseaudio patched to attempt to snd_pcm_recover() upon receiving an error from snd_pcm_rewind().
