ALSA: usb-audio: fix broken logic in snd_audigy2nx_led_update()

Browse source

When the support for the Sound Blaster X-Fi Surround 5.1 Pro was added,
the existing logic for the X-Fi Surround 5.1 in snd_audigy2nx_led_put()
was broken due to missing *else* before the added *if*: snd_usb_ctl_msg()
became incorrectly called twice and an error from first snd_usb_ctl_msg()
call ignored.  As the added snd_usb_ctl_msg() call was totally identical
to the existing one for the "plain" X-Fi Surround 5.1, just merge those
two *if* statements while fixing the broken logic...
