ALSA: rawmidi: Pass rawmidi directly to snd_rawmidi_kernel_open()
snd_rawmidi_kernel_open() is used only internally from ALSA sequencer,
so far, and parsing the card / device matching table at each open is
redundant, as each sequencer client already gets the rawmidi object
beforehand.
This patch optimizes the path by passing the rawmidi object directly
at snd_rawmidi_kernel_open(). This is also a preparation for the
upcoming UMP rawmidi I/O support.
