wifi: iwlwifi: mld: set correct key mask for NAN

Browse source 
For NAN data, the supplicant may derive and install GTKs to
transmit with. As multicast data encryption is supported only
with firmware versions that support adding NAN multicast
data station, allow GTK installation only with such FW
versions. Otherwise, do not install the GTK to the device.

For NAN management, there are no GTKs, but there are IGTKs
and BIGTKs, which need to be installed for the NAN broadcast
and NAN management stations. This is supported only with
firmware versions that allow adding NAN broadcast station
and NAN management station.

Handle both of these cases by adjusting the station mask
appropriately, returning a zero station mask for the GTK
and allowing that to not be an error/warning message.
