fix gethostby*_r result pointer value on error
according to the documentation in the man pages, the GNU extension
functions gethostbyaddr_r, gethostbyname_r and gethostbyname2_r are
guaranteed to set the result pointer to NULL in case of error or no
result.
corresponds to commit fe82bb9b921be34370e6b71a1c6f062c20999ae0 in
master branch.
