wifi: iwlwifi: mld: add support for nan schedule config command version 2

Browse Source 
Version 2 of the NAN schedule config command adds support for deferred
schedule update and passing the availability attribute blob to
firmware.
Add support for the new command version. Currently the new
functionality is not supported.
