bpf: pass bpf_struct_ops_link to callbacks in bpf_struct_ops.
Pass an additional pointer of bpf_struct_ops_link to callback function reg,
unreg, and update provided by subsystems defined in bpf_struct_ops. A
bpf_struct_ops_map can be registered for multiple links. Passing a pointer
of bpf_struct_ops_link helps subsystems to distinguish them.
This pointer will be used in the later patches to let the subsystem
initiate a detachment on a link that was registered to it previously.
