SME: Clear possibly used WPA/RSN IE for new connection

This was already done in the case SME in the driver is used, but the SME
code path was resetting the local WPA/RSN IE only for association. While
that was fine for existing use cases, FILS needs a new RSN IE to be set
for PMKSA caching case in Authentication frames, so clear the local IE
before starting new authentication.
