Adrian Hunter ca76d7d281 perf record: Fix cpu mask bit setting for mixed mmaps 
With mixed per-thread and (system-wide) per-cpu maps, the "any cpu" value
 -1 must be skipped when setting CPU mask bits.

Prior to commit cbd7bfc7fd ("tools/perf: Fix out of bound access
to cpu mask array") the invalid setting went unnoticed, but since then
it causes perf record to fail with an error.

Example:

 Before:

   $ perf record -e intel_pt// --per-thread uname
   Failed to initialize parallel data streaming masks

 After:

   $ perf record -e intel_pt// --per-thread uname
   Linux
   [ perf record: Woken up 1 times to write data ]
   [ perf record: Captured and wrote 0.068 MB perf.data ]

Fixes: ae4f8ae16a ("libperf evlist: Allow mixing per-thread and per-cpu mmaps")
