qcacld-3.0: Route the legacy NAN commands through NAN component

NAN component has been moved to CLD. It includes implementation
of the new NAN command QCA_NL80211_VENDOR_SUBCMD_NAN_EXT.
Change the legacy NAN implementation of vendor cmd
QCA_NL80211_VENDOR_SUBCMD_NAN so that the requests go
through the NAN component. Clean up the legacy path.
Functionality remains unchanged for legacy command.

Route the legacy NAN commands through the NAN component.
