usb: gadget: f_ncm: obtain cdev from function instead of driver_data

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

The 'driver_data' field in ep0 is never set to pointer to cdev, so we
have to obtain it from another source as in this context ep->driver_data
contains invalid data.
