Fix an error check in check_target.

Browse Source 
There was a missing level of deference on the pointers, so a condition
was never true in normal use. The effect was that check_target could
return without haveing put something in *addr, the previous contents of
which would later be passed to getaddrinfo, causing a "Name or service
not known" error.
