perf probe: Fix examples section of documentation
commit d89269a89ebb6a74512f3f40e89cd12017f60a75 upstream.
An example in perf-probe documentation for pattern of function name
based probe addition is not providing example command for that case.
This commit fixes the example to give appropriate example command.
