tracing/core: fix early free of cpumasks
upstream commit: 2fc1dfbe17e7705c55b7a99da995fa565e26f151
Impact: fix crashes when tracing cpumasks
While ring-buffer allocation, the cpumasks are allocated too,
including the tracing cpumask and the per-cpu file mask handler.
But these cpumasks are freed accidentally just after.
Fix it.
