Numfor Mbiziwo-Tiapo 3b8c4eae55 perf test mmap-thread-lookup: Initialize variable to suppress memory sanitizer warning 
[ Upstream commit 4e4cf62b37 ]

Running the 'perf test' command after building perf with a memory
sanitizer causes a warning that says:

  WARNING: MemorySanitizer: use-of-uninitialized-value... in mmap-thread-lookup.c

Initializing the go variable to 0 silences this harmless warning.

Committer warning:

This was harmless, just a simple test writing whatever was at that
sizeof(int) memory area just to signal another thread blocked reading
that file created with pipe(). Initialize it tho so that we don't get
this warning.
