i40e: Fix for failed to init adminq while VF reset
Fix for failed to init adminq: -53 while VF is resetting via MAC address changing procedure. Added sync module to avoid reading deadbeef value in reinit adminq during software reset. Without this patch it is possible to trigger VF reset procedure during reinit adminq. This resulted in an incorrect reading of value from the AQP registers and generated the -53 error.
