Don't rescue IPAddr::InvalidAddressError

IPAddr::InvalidAddressError does not exist in Ruby 1.9.3

As IPAddr::InvalidAddressError is a subclass of ArgumentError
(via IPAddr::Error) just rescuing ArgumentError is fine.

This reverts commit 16fe19831548f108c113094d106663497fc190d5, reversing
changes made to 4c81c8ce533896be28bdc0b055ff30bb9dee1316.
