kfifo: fix kfifo_to_user() return type
The kfifo_to_user() macro is supposed to return zero for success or
negative error codes. Unfortunately, there is a signedness bug so it
returns unsigned int. This only affects callers which try to save the
result in ssize_t and as far as I can see the only place which does that
is line6_hwdep_read().
TL;DR: s/_uint/_int/.
