FT: Clear SME FT data on disassoc

SME ft_used flag is sometimes not cleared on disassoc. For example,
after initial FT connection, ft_used is set while ft_ies stays NULL.
Later on, upon disassoc, sme_update_ft_ies() is not invoked and ft_used
is not cleared. Fix this by invoking sme_update_ft_ies() also in case
ft_used is set.

This is needed to fix an issue with drivers that use nl80211 Connect API
with FT and expect to the NL80211_AUTHTYPE_OPEN specified in the Connect
command for the initial mobility domain association.
