Correctly copy the target host identification in PQcancelCreate. PQcancelCreate failed to copy struct pg_conn_host's "type" field, instead leaving it zero (a/k/a CHT_HOST_NAME). This seemingly has no great ill effects if it should have been CHT_UNIX_SOCKET instead, but if it should have been CHT_HOST_ADDRESS then a null-pointer dereference will occur when the cancelConn is used.
