ALSA: rawmidi: Return the error from snd_rawmidi_input_params()

Browse source

The snd_rawmidi_input_params() computes err for the three invalid mode
combinations and for resize_runtime_buffer(), applies the new framing
and clock type only when err is zero, and then returns 0 anyway.  A
caller that asked for parameters the kernel rejected is told the change
succeeded, and the substream keeps its old buffer.

The open_mutex conversion turned the early returns into assignments.
It handled the output sibling correctly, which still returns err, and
left this one behind.
