ALSA: usb-audio: Avoid false E-MU sample-rate notifications
snd_emuusb_set_samplerate() unconditionally notifies the E-MU
SampleRate Extension Unit control after issuing SET_CUR.
If snd_usb_mixer_set_ctl_value() fails, the control value has not
changed, yet snd_usb_mixer_notify_id() still invalidates the cache and
emits a value-change event to userspace.
Notify the control only after a successful write.
Fixes: 7d2b451e65d2 ("ALSA: usb-audio - Added functionality for E-mu 0404USB/0202USB/TrackerPre")
