Andrii Nakryiko 2fe8890848 bpf: Keep module's btf_data_size intact after load ...

Having real btf_data_size stored in struct module is benefitial to quickly
determine which kernel modules have associated BTF object and which don't.
There is no harm in keeping this info, as opposed to keeping invalid pointer.
