Use host.ip, not just (undefined) ip in whois.nse exception error

messages. Instead of handling an error nicely, it caused a format string
error of its own:
./nselib/stdnse.lua:61: bad argument #3 to 'format' (string expected, got nil)
It seems that a deadlock happens immediately after one of these errors
occurs. This change doesn't fix the deadlock but allows the underlying
error message to be printed.
