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

commit b44be2462dbe3e23f0aedff64de52a1e8e47a1cd upstream.

Commit 3b74c73f8d6f053f422e85fce955b61fb181cfe7 switched over to memdup_user()
in ep_write() function and removed kfree (kbuf).
memdup_user() function allocates memory which is never freed.
