tracing: make PREEMPTIRQ_EVENTS depend on TRACING
When CONFIG_TRACING is disabled, the new preemptirq events tracer
produces a build failure:
In file included from kernel/trace/trace_irqsoff.c:17:0:
kernel/trace/trace.h: In function 'trace_test_and_set_recursion':
kernel/trace/trace.h:542:28: error: 'struct task_struct' has no member named 'trace_recursion'
Adding an explicit dependency avoids the broken configuration.
