[PATCH 1/5] ALSA: usb-audio: localize one-referrer variable

[Takashi Sakamoto <o-takashi@sakamocchi.jp>]

When accessed by one referrer inner a file, variables should have static
qualifier to declare local-linkage.

This commit fixes the bug. Sparse generated below warnings.
sound/usb/mixer_us16x08.c:156:13: warning: duplicate const
sound/usb/mixer_us16x08.c:156:18: warning: symbol 'route_names' was not declared. Should it be static?
