Naresh reported that test_align fails because of the mismatch at the
verbose printout of the register states. The reason is due to the newly
added ref_obj_id.
ref_obj_id is only useful for refcounted reg. Thus, this patch fixes it
by only printing ref_obj_id for refcounted reg. While at it, it also uses
comma instead of space to separate between "id" and "ref_obj_id".
Fixes: 1b98658968 ("bpf: Fix bpf_tcp_sock and bpf_sk_fullsock issue related to bpf_sk_release")
