tools: cpupower: Fix error when running cpupower monitor
get_cpu_topology() tries to get topology info from all cpus by reading files in the topology sysfs dir. If a cpu is offlined, since it doesn't have topology dir, this function fails and returns -1. This causes functions relying on get_cpu_topology() to fail. For example- $ cpupower monitor Cannot read number of available processors Fix this by skipping fetching topology info for offline cpus.
