Kunpeng930 could be able to close master ooo when NFE occurs, which will
disable memory accessing from device and execute tasks. This ensures that
errors do not spread.

This patch enables the hardware to close master ooo when an error occurs
by writing hardware registers, and ensures that the driver will not drain
qp because the hardware will empty the tasks automatically.

In order to avoid reporting an exception but the error type is not
configured, the driver needs to configure the error type first, and then
enable the error interrupt. Before executing the task, hardware error
initialization is needed so that the hardware can detect the error in time.

The HW overwrites destination always when sg_nents() > 1.
The problem seems that the HW always write areq->cryptlen bytes on the
last SG.
A comment in driver's code seems to give a clue that multiple SG was not
