UPSTREAM: usb: gadget: f_fs: Fix use-after-free
(cherry picked from commit 38740a5b87d53ceb89eb2c970150f6e94e00373a)
When using asynchronous read or write operations on the USB endpoints the
issuer of the IO request is notified by calling the ki_complete() callback
of the submitted kiocb when the URB has been completed.
Calling this ki_complete() callback will free kiocb. Make sure that the
structure is no longer accessed beyond that point, otherwise undefined
behaviour might occur.
