bpftool: Fix maybe-uninitialized warnings
[ Upstream commit 4bbb3583687051ef99966ddaeb1730441b777d40 ]
Somehow when bpftool is compiled in -Og mode, compiler produces new warnings
about possibly uninitialized variables. Fix all the reported problems.
Fixes: 2119f2189df1 ("bpftool: add C output format option to btf dump subcommand")
