usb: gadget: f_subset: Fix unbalanced refcnt in geth_free

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_subset: Fix unbalanced refcnt in geth_free geth_alloc() increments the reference count, but geth_free() fails to decrement it. This prevents the configuration of attributes via configfs after unlinking the function. Decrement the reference count in geth_free() to ensure proper cleanup.
