wifi: iwlwifi: mvm: don't request statistics in restart

Browse Source 
During restart mac80211 notifies the driver about the association,
(if we was associated before the restart) which causes the driver to
request statistics from the FW. This causes to an immediate exit from
EMLSR after the restart is done, when the statistics notif is handled.
(too low TPT). There is no point in requesting statistics wnyway, since
the FW just started and don't have any.
