Hou Tao 00cdcd2900 selftests/bpf: Don't use libbpf_get_error() in kprobe_multi_test
Since libbpf v1.0, libbpf doesn't return error code embedded into the
pointer iteself, libbpf_get_error() is deprecated and it is basically
the same as using -errno directly.

So replace the invocations of libbpf_get_error() by -errno in
kprobe_multi_test. For libbpf_get_error() in test_attach_api_fails(),
saving -errno before invoking ASSERT_xx() macros just in case that
errno is overwritten by these macros. However, the invocation of
libbpf_get_error() in get_syms() should be kept intact, because
hashmap__new() still returns a pointer with embedded error code.
