HID: prodikeys: constify snd_rawmidi_ops structures

JuliaLawall · Jiri Kosina · commit 0acb310c3273 · 2017-08-15T11:02:45.000+02:00
This snd_rawmidi_ops structure is only passed as the third
argument of snd_rawmidi_set_ops.  This argument is const, so the
snd_rawmidi_ops structure can be const too.

Done with the help of Coccinelle.
