net: FIX ipv6_forward sysctl restart
Just returning -ERESTARTSYS without a signal pending is not
good that will just leak it to userspace. We need return
-ERESTARTNOINTR so we always restart and set signal pending
so that we fall of the fast path of syscall return and setup
the system call restart.
So use restart_syscall() which does all of this for us.
