perf tools: Fix calloc() arguments to address error introduced in gcc-14
the definition of calloc is as follows:
void *calloc(size_t nmemb, size_t size);
number of members is in the first parameter and the size is in the
second parameter.
Fix error messages on gcc 14 20240102:
error: 'calloc' sizes specified with 'sizeof' in the earlier argument and
not in the later argument [-Werror=calloc-transposed-args]
Committer notes:
I noticed this on fedora 40 and rawhide.
