runtime: crash in race detector when execution tracer reads from CPU profile buffer [1.22 backport]

[gopherbot]

@prattmic requested issue #65607 to be considered for backport to the next 1.22 minor release.

@gopherbot Please backport to 1.22. This causes random crashes when using race+trace+cpu profiling.
