USB: f_fs: Avoid using completion variable on stack
done completion variable is local stack variable to ffs_epfile_io().
It is being used to unblock ffs_epfile_io() from USB request
completion context where done is accessed through req->context. If
ffs_epfile_io() is unblocked or interrupted due to epfile close or
any signal before USB request completion is handled, req->context is
having stale "done" reference causing invalid access. Fix this issue
by storing done completion reference with epfile structure instead of
having it on stack to have valid req->context in completion handler.
