perf tests evsel-tp-sched: Fix bitwise operator
commit 489338a717a0dfbbd5a3fabccf172b78f0ac9015 upstream.
Notice that the use of the bitwise OR operator '|' always leads to true
in this particular case, which seems a bit suspicious due to the context
in which this expression is being used.
Fix this by using bitwise AND operator '&' instead.
This bug was detected with the help of Coccinelle.
