tracing: Replace the static global per_cpu arrays with allocated per_cpu
The global and max-tr currently use static per_cpu arrays for the CPU data descriptors. But in order to get new allocated trace_arrays, they need to be allocated per_cpu arrays. Instead of using the static arrays, switch the global and max-tr to use allocated data. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
