ALSA: oxfw: fix regression to handle Stanton SCS.1m/1d
commit 3d016d57fdc5e6caa4cd67896f4b081bccad6e2c upstream. At a commit 6c29230e2a5f ("ALSA: oxfw: delayed registration of sound card"), ALSA oxfw driver fails to handle SCS.1m/1d, due to -EBUSY at a call of snd_card_register(). The cause is that the driver manages to register two rawmidi instances with the same device number 0. This is a regression introduced since kernel 4.7. This commit fixes the regression, by fixing up device property after discovering stream formats.
