tracing: Fix number of entries in trace header
commit 9e7382153f80ba45a0bbcd540fb77d4b15f6e966 upstream. The following commit 441dae8f ("tracing: Add support for display of tgid in trace output") removed the call to print_event_info() from print_func_help_header_irq() which results in the ftrace header not reporting the number of entries written in the buffer. As this wasn't the original intent of the patch, re-introduce the call to print_event_info() to restore the orginal behaviour.
