perf data convert: Fix segfault when converting to json when cpu_desc isn't set
Arm64 doesn't have Model in /proc/cpuinfo and, thus, cpu_desc doesn't get
assigned.
Running
$ perf data convert --to-json perf.data.json
ends up calling output_json_string() with NULL pointer, which causes a
segmentation fault.
