crypto: hisilicon/qm - adjust order of device error configuration

mainline inclusion
from mainline-master
commit 3b9c24de
category: bugfix
bugzilla: 173981
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3b9c24dec891d418e26032709d6f01fe3757a4a6

----------------------------------------------------------------------

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.
