usb: gadget: uvc: configfs: Drop leaked references to config items
[ Upstream commit 86f3daed59bceb4fa7981d85e89f63ebbae1d561 ]
Some of the .allow_link() and .drop_link() operations implementations
call config_group_find_item() and then leak the reference to the
returned item. Fix this by dropping those references where needed.
