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