wifi: iwlwifi: mvm: fix the key PN index
When waking from D3 (and a GTK rekey happened during
D3), the key itself is saved in iwl_wowlan_status_data::gtk
array, but the PN is saved in iwl_wowlan_status_data::gtk_seq
array.
The indices (of the same key) might differ in both arrays.
Fix using the gtk array index in the gtk_seq array.
Rather, iterate and search for the correct key in the
gtk_seq array.
