libperf threadmap: Don't segv for index 0 for the NULL 'struct perf_thread_map' pointer
perf_thread_map__nr() returns length 1 if the perf_thread_map is NULL,
meaning index 0 is valid.
When perf_thread_map__pid() of index 0 is read then return the expected
"any" -1 value.
Assert this is only done for index 0.
