[PATCH 12/12] tracing: Remove unused buffer_page field from trace_array_cpu structure

[Steven Rostedt]

From: Steven Rostedt <rostedt@xxxxxxxxxxx>

The trace_array_cpu had a "buffer_page" field that was originally going to
be used as a backup page for the ring buffer. But the ring buffer has its
own way of reusing pages and this field was never used.

Remove it.
