[PATCH 15/92] wpa_supplicant: Set NAN Identity Key and its lifetime to NAN module

[Andrei Otcheretianski]

From: Avraham Stern <avraham.stern at intel.com>

Set the NAN Identity Key to a random value on init, and set its
default lifetime to 12 hours. The option to set the NAN Identity Key
from control interface will be added in a later patch.
