qcacld-3.0: Zero RIC pointer if RIC len is 0

Currently ric_ies pointer of struct cfg80211_ft_event_params is pointer
of local stack, even RIC len is 0. It introduced MIC mismatch when H2E
enabled between STAUT and AP.

Change to assign valid RIC pointer only when RIC len greater than 0.
This function only valid for LFR2.0 FT roaming.
