Namhyung Kim bd57a9f33a perf daemon: Fix compile error with Asan 
I'm seeing a build failure when build with address sanitizer.  It seems
we could write to the name[100] if the var is longer.

  $ make EXTRA_CFLAGS=-fsanitize=address
  ...

  In function ‘get_session_name’,
    inlined from ‘session_config’ at builtin-daemon.c:164:6,
