[PATCH 4/6] transport: fix index in ipv6 connection failed message

[Jonathan Nieder <jrnieder@gmail.com>]

Ever since v1.5.3-rc0~185^2~1 (Verbose connect messages to show
the IP addresses used, 2007-05-23), git's ipv4 connection failure
messages have looked something like

	git.example.com[2: 127.0.0.1]: errno=Network Unreachable

The increasing index ("2" above) indicates which item in the list of
addresses returned by gethostbyname was being tried so the operator
can tell that git was not just trying to resolve the same hostname
again and again.

The ipv6 codepath prints something similar, but the counter is never
incremented so the index is always "0".  Fix it.
