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

[Ingo Molnar]

this warning:

 kernel/trace/trace.c: In function âtrace_vprintkâ:
 kernel/trace/trace.c:3626: warning: âflagsâ 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.
