Andrii Nakryiko 02670deede libbpf: Handle unsupported mmap-based /sys/kernel/btf/vmlinux correctly ... libbpf_err_ptr() helpers are meant to return NULL and set errno, if there is an error. But btf_parse_raw_mmap() is meant to be used internally and is expected to return ERR_PTR() values. Because of this mismatch, when libbpf tries to mmap /sys/kernel/btf/vmlinux, we don't detect the error correctly with IS_ERR() check, and never fallback to old non-mmap-based way of loading vmlinux BTF. Fix this by using proper ERR_PTR() returns internally.
