Commit 477673d6f3 ("send-pack: support push negotiation", 2021-05-05)
did not test the case in which a remote advertises at least one ref. In
such a case, "remote_refs" in get_commons_through_negotiation() in
send-pack.c would also contain those refs with a zero ref->new_oid (in
addition to the refs being pushed with a nonzero ref->new_oid). Passing
them as negotiation tips to "git fetch" causes an error, so filter them
out.
(The exact error that would happen in "git fetch" in this case is a
segmentation fault, which is unwanted. This will be fixed in the
subsequent commit.)
