[PATCH] usb: gadget: uvc: Missing files for configfs interface

[Bin Liu <b-liu@ti.com>]

From: Petr Cvek <petr.cvek@tul.cz>

commit c8cd751060b149997b9de53a494fb1490ded72c5 upstream.

Commit 76e0da34c7ce ("usb-gadget/uvc: use per-attribute show and store
methods") caused a stringification of an undefined macro argument "aname",
so three UVC parameters (streaming_interval, streaming_maxpacket and
streaming_maxburst) were named "aname".

Add the definition of "aname" to the main macro and name the filenames as
originaly intended.
