ALSA: oxfw: fix regression to handle Stanton SCS.1m/1d
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.
