tracing: fix recursive test level calculation

Browse source

The recursive tests to detect same level recursion in the ring buffers
did not account for the hard/softirq_counts to be shifted. Thus the
numbers could be larger than then mask to be tested.

This patch includes the shift for the calculation of the irq depth.

[ Impact: stop false positives in trace recursion detection ]
