[PATCH AUTOSEL for 3.18 02/16] usb: gadget: configs: plug memory leak

[alexander.levin@verizon.com]

From: John Keeping <john@metanate.com>

[ Upstream commit 38355b2a44776c25b0f2ad466e8c51bb805b3032 ]

When binding a gadget to a device, "name" is stored in gi->udc_name, but
this does not happen when unregistering and the string is leaked.
