usb: gadget: net2280: Fix double free in probe error path

usb_initialize_gadget() installs gadget_release() as the release
callback for the embedded gadget device.  The struct net2280 instance is
therefore released through gadget_release() when the gadget device's last
reference is dropped.

The probe error path calls net2280_remove(), which tears down the
partially initialized device and drops the gadget reference with
usb_put_gadget().  Calling kfree(dev) afterwards can free the same object
again.

Drop the explicit kfree() and let the gadget device release callback
handle the final free.  This issue was found by a static analysis tool
I am developing.
