tracing: Remove access to trace_flags in trace_printk.c
In the effort to move the global trace_flags to the tracing instances, the direct access to trace_flags must be removed from trace_printk.c Instead, add a new trace_printk_enabled boolean that is set by a new access function trace_printk_control(), that will enable or disable trace_printk.
