um: fix global timer issue when using CONFIG_NO_HZ
commit 482db6df1746c4fa7d64a2441d4cb2610249c679 upstream. This fixes a issue which was introduced by fe2cc53e ("uml: track and make up lost ticks"). timeval_to_ns() returns long long and not int. Due to that UML's timer did not work properlt and caused timer freezes.
