network: use void* to correctly store SetLinkOperation in Request

Previously, when `link_request_queue()` is called in link_request_set_link(),
`SetLinkOperation` is casted with INT_TO_PTR(), and the value is assigned to
`void *object`. However the value was read directly through the member
`SetLinkOperation set_link_operation` of the union which `object`
beloging to. Thus, read value was always 0 on big-endian systems.

Fixes configuring link issue on s390x systems.
