Subject: bpftool: Fix uninit variable compilation warning
Patch-mainline: v5.18-rc1
Git-commit: a9a8ac592e47ff35363308ad4c66740724132aa3
References: jsc#PED-1377

Newer GCC complains about capturing the address of unitialized variable.
While there is nothing wrong with the code (the variable is filled out
by the kernel), initialize the variable anyway to make compiler happy.
