qcacld-3.0: Handle dummy wmi_radio_link_stats_link wmi event

Browse Source 
Sometimes wlan FW fails to return wmi_radio_link_stats_link because of
buffer, which makes timeout happen in wlan_hdd_cfg80211_ll_stats_get.

To fix this issue, FW returns wmi_radio_link_stats_link with dummy
information, and host need handle dummy wmi_radio_link_stats_link wmi
event.
