David Michael 76c6303530 libbpf: Fix uninitialized warning in btf_dump_dump_type_data 
commit dfd0afbf15 upstream.

GCC 11.3.0 fails to compile btf_dump.c due to the following error,
which seems to originate in btf_dump_struct_data where the returned
value would be uninitialized if btf_vlen returns zero.

btf_dump.c: In function ‘btf_dump_dump_type_data’:
btf_dump.c:2363:12: error: ‘err’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
 2363 |         if (err < 0)
      |            ^

Fixes: 920d16af9b ("libbpf: BTF dumper support for typed data")
