Andrii Nakryiko e18e2e70db libbpf: handle yet another corner case of nulling out struct_ops program 
There is yet another corner case where user can set STRUCT_OPS program
reference in STRUCT_OPS map to NULL, but libbpf will fail to disable
autoload for such BPF program. This time it's the case of "new" kernel
which has type information about callback field, but user explicitly
nulled-out program reference from user-space after opening BPF object.

Fix, hopefully, the last remaining unhandled case.

Fixes: 0737df6de946 ("libbpf: better fix for handling nulled-out struct_ops program")
Fixes: f973fccd43d3 ("libbpf: handle nulled-out program in struct_ops correctly")
