sound: rawmidi: fix MIDI device O_APPEND error handling
Commit 9a1b64caac82aa02cb74587ffc798e6f42c6170a in 2.6.30 broke the error handling code in rawmidi_open_priv(). If only the output substream of a RawMIDI device has been opened and if this device is then opened with O_RDWR | O_APPEND and if the initialization of the input substream fails (either because of low memory or because the device driver's open callback fails), then the runtime structure of the already open output substream will be freed and all following writes through the first handle will cause snd_rawmidi_write() to use the NULL runtime pointer.
