[TSAN] Fix tsan on FreeBSD after D54889
Summary:
It appears that since https://reviews.llvm.org/D54889, BackgroundThread()
crashes immediately because cur_thread()-> will return a null pointer
which is then dereferenced. I'm not sure why I only see this issue on
FreeBSD and not Linux since it should also be unintialized on other platforms.
