Convert st_ops->data to the shadow type of the struct_ops map. The shadow type of a struct_ops type is a variant of the original struct type providing a way to access/change the values in the maps of the struct_ops type. bpf_map__initial_value() will return st_ops->data for struct_ops types. The skeleton is going to use it as the pointer to the shadow type of the original struct type. One of the main differences between the original struct type and the shadow type is that all function pointers of the shadow type are converted to pointers of struct bpf_program. Users can replace these bpf_program pointers with other BPF programs. The st_ops->progs[] will be updated before updating the value of a map to reflect the changes made by users.
