Series crypto: hisilicon - fix issues related to device reset | expand

Commit Message

The timeout threshold of the hpre cluster is 16ms. When the CPU
and device share virtual address, page fault processing time may
exceed the threshold.

In the current test, there is a high probability that the
cluster times out. However, the cluster is waiting for the
completion of memory access, which is not an error, the device
does not need to be reset. If an error occurs in the cluster,
qm also reports the error. Therefore, the cluster timeout
error of hpre can be masked.
