[PATCH 4.14 0/2] usb: gadget: use after free in dev_config

Author: Hangyu Hua hbh25y@gmail.com commit 89f3594d0de5 ("usb: gadget: don't release an existing dev->buf")

Author: Hangyu Hua hbh25y@gmail.com commit 501e38a5531e ("usb: gadget: clear related members when goto fail")

Add two commits to all stable branches.

There are two bugs: dev->buf does not need to be released if it already exists before executing dev_config. dev->config and dev->hs_config and dev->dev need to be cleaned if dev_config fails to avoid UAF.
