ftrace-graph: show latency-format on print_graph_irq()

On the function_graph tracer, the print_graph_irq() function prints a
trace line with the flag ==========> on an irq handler entry, and the
flag <========== on an irq handler return.

But when the latency-format is enable, it is not printing the
latency-format flags, causing the following error in the trace output:

 0)   ==========> |
 0)  d...              |  smp_apic_timer_interrupt() {

This patch fixes this issue by printing the latency-format flags when
it is enable.
