Simon Grätzer d9d3cacaf5 Add a missing define to monitoring/iostats_context_imp.h (#5136)
Summary:
I think when PR https://github.com/facebook/rocksdb/pull/4889 added the `IOSTATS_CPU_TIMER_GUARD` define to this header file, the noop version in the `#else` branch was forgotten.

Not sure if this is common, but on my MacOS machine it breaks my build
