usb: gadget: gadgetfs: Free memory allocated by memdup_user() 



commit b44be2462dbe3e23f0aedff64de52a1e8e47a1cd upstream.

Commit 3b74c73f switched over to memdup_user()
in ep_write() function and removed kfree (kbuf).
memdup_user() function allocates memory which is never freed.

Fixes: 3b74c73f (usb: gadget: inode: switch over to memdup_user())
