tracing/function-graph-tracer: fix 'flags' variable mismatch

Browse source 
this warning:

 kernel/trace/trace.c: In function ‘trace_vprintk’:
 kernel/trace/trace.c:3626: warning: ‘flags’ may be used uninitialized in this function

shows some confusion about irq_flags / flags use here. We already have
irq_flags so remove the extra flags variable.
