[PATCH] t/helper/test-lazy-name-hash: fix compilation

[Stefan Beller]

I was compiling origin/master today with the DEVELOPER compiler flags
today and was greeted by

t/helper/test-lazy-init-name-hash.c: In function ‘cmd_main’:
t/helper/test-lazy-init-name-hash.c:172:5: error: ‘nr_threads_used’ may be used 
uninitialized in this function [-Werror=maybe-uninitialized]
     printf("avg [size %8d] [single %f] %c [multi %f %d]\n",
     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
         nr,
         ~~~
         (double)avg_single/1000000000,
         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
         (avg_single < avg_multi ? '<' : '>'),
         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
         (double)avg_multi/1000000000,
         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
         nr_threads_used);
         ~~~~~~~~~~~~~~~~
t/helper/test-lazy-init-name-hash.c:115:6: note: ‘nr_threads_used’ was declared 
here
  int nr_threads_used;
      ^~~~~~~~~~~~~~~

Fix this issue by assigning 0 to 'nr_threads_used'.

Slightly reworded the commit message. I'd really like this patch to be included
such that I can compile git with the DEVELOPER_CFLAGS flags.
