fix(profiling): reduce lock profiler log spam [backport 2.16]

[github-actions]

Backport 079e478 from #11377 to 2.16.

The lock profiler would log a warning if it couldn't determine a
name for a lock, and it would try determining a name multiple times for
the same lock. This lead to excessive log spam. Downgrade this to a
debug log and only try to determine the name once.
