wifi: iwlwifi: mvm: skip short statistics window when updating EMLSR

The statistics are not synchronized with the time that we enter EMLSR.
This means that we can receive the statistic notification just after
having cleared the counters, causing us to immediately exit EMLSR again.

Fix this by checking that most of the time for the window has passed. If
that is not the case, ignore this window and wait for the next
notification.
