[PATCH] objtool: Fix -Wformat-truncation seen with GCC 12.

[Martin Liška]

The patch fixes the following warning that seems reasonable:

check.c:2836:58: error: '%d' directive output may be truncated writing between 1 and 10 bytes into a region of size 9 [-Werror=format-truncation=]
2836 |                 snprintf(pvname, sizeof(pvname), "pv_ops[%d]", idx);
