The snd_pcm_oss_writev3() and snd_pcm_oss_readv3() are used only in io.c with CONFIG_SND_PCM_OSS_PLUGINS=y. Add an ifdef to reduce the build of these functions.
Along with it, since they are called always for in-kernel copy, reduce the argument and call snd_pcm_kernel_writev() and *_readv() directly instead.
