crypto: hisilicon/qm - fix EQ/AEQ interrupt issue
During hisilicon accelerator live migration operation. In order to
prevent the problem of EQ/AEQ interrupt loss. Migration driver will
trigger an EQ/AEQ doorbell at the end of the migration.
This operation may cause double interruption of EQ/AEQ events.
To ensure that the EQ/AEQ interrupt processing function is normal.
The interrupt handling functionality of EQ/AEQ needs to be updated.
Used to handle repeated interrupts event.
Fixes: b0eed085903e ("hisi_acc_vfio_pci: Add support for VFIO live migration")
