crypto: qat - notify fatal error before AER reset preparation

Browse Source 
Send fatal error notifications to subsystems and VFs as soon as
AER error detection starts, before entering the reset preparation
shutdown sequence.

This reduces notification latency and ensures peers are informed
immediately on fatal detection, rather than after restart-state setup
and arbitration teardown.
