ipa: Fix client setting unit_id with ASP name instead of AS
This was broken since ever. The client was submitting the ASP name
in the unit_id field during IPA handshake, and the server was
expecting it to contain the AS, so it failed with message:
"Cannot find any definition for IPA Unit Name '%s'" in
ipa_asp_fsm_wait_id_resp().
