Using QAT on a Hygon CPU

Can QAT work properly on a Hygon CPU and ensure normal performance?

```
Distribution Name Kylin V10 SP3 2403
Distribution Version 9.7
Kernel Version 4.19.90-89.11.v2401.ky10.x86_64
Architecture x86_64
qat Version 4.20.0
zfs Version 2.2.4-1
```

There are issues with read performance when using ZFS compression together with QAT.During the fio test, read performance drops a lot.

```
--qat
mkdir -p /opt/qat
tar -xvf QAT.L.4.20.0-00001.tar.gz
./configure --enable-kapi
make -j$(nproc)
make install

--zfs
./configure --with-qat=/opt/qat
make -j$(nproc)
make install
ldconfig && depmod -a
modprobe zfs

zpool create datapool raidz /dev/nvme2n1 /dev/nvme3n1 /dev/nvme4n1 /dev/nvme5n1 -o listsnapshots=on -O atime=off -O primarycache=metadata -o ashift=12 -f
zfs create -o volblocksize=32k -o refreservation=0B -o compression=gzip -V 1000G datapool/datatest

No source file or project test is named. Start by reviewing the reported QAT 4.20.0 and ZFS 2.2.4 setup, then reproduce the fio read comparison on the Hygon CPU; the issue is resolved when QAT and ZFS compression no longer cause the reported read-performance drop or its cause is clearly identified.
