Fix authentication algorithm negotiation in SME code

Commit 6ac4b15ef8 (wpa_radio work for
connection) caused a regression for cases where multiple auth_alg values
are set in a network block and wpa_supplicant-based SME is supposed to
iterate through them. The connection radio work was not terminated when
receiving authentication failure and this resulted in the following
authentication attempt failing.
