qcacld-3.0: Remove unused wlan_hdd_cfg80211_nan_*() stubs

Change I542e5afe832619f8c088220cc4456aa7fe4416fd ("qcacld-3.0: Route
the legacy NAN commands through NAN component") removed function
wlan_hdd_cfg80211_nan_callback(), but left behind the stub
implementation that was referenced when the NAN feature was not
enabled. This stub is unused, so remove it.

In addition functions wlan_hdd_cfg80211_nan_request() and
wlan_hdd_cfg80211_nan_ext_request() are only referenced when the NAN
feature is enabled, so the stub functions are also unnecessary, so
remove those as well.

Finally, wlan_hdd_cfg80211_nan_request() has two separate prototypes,
so remove one of the duplicates.
