bpftool: Check for NULL ptr of btf in codegen_asserts bpf_object__btf() can return a NULL value. If bpf_object__btf returns null, do not progress through codegen_asserts(). This avoids a null ptr dereference at the call btf__type_cnt() in the function find_type_for_map() Signed-off-by: Michael Mullin <masmullin@gmail.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20220523194917.igkgorco42537arb@jup
