crypto: hisilicon/qm - enable to close master ooo when NFE occurs
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.
