eap_proxy: On SIM error flush PMKSAs only for SIM/AKA/AKA' networks

Browse source 
Previously, SIM state change with SIM_STATE_ERROR cleared all PMKSA
entries (including non-SIM networks). Limit this to networks which use
SIM-based authentication methods to avoid unnecessarily removal of PMKSA
entries.
