Reorder XML-RPC initialization in ipa-join to avoid segfault.

Browse Source 
There were a number of code paths where we would try to call
xmlrpc_env_clean() without having first called xmlrpc_env_init()
Re-order the code so we always initialize the XML-RPC client first.

I also noticed a place where the return value of strdup() was not
being checked for NULL.
