ao_oss: assume audio format reinit is not needed with SNDCTL_DSP_RESET

Browse Source 
I have no idea whether this is true, because there literally doesn't
seem to exist documentation for SNDCTL_DSP_RESET. But at least on
Linux' OSS emulation, it is true. Also, it would be quite insane if
it would be needed.
