crypto: hisilicon/qm - add the save operation of eqe and aeqe

The eqe and aeqe are device updated values that include the
valid bit and queue number. In the current process, there is no
memory barrier added, so it cannot be guaranteed that the valid
bit is read before other processes are executed. Since eqe and aeqe
are only 4 bytes and the device writes them to memory in a single
operation, saving the values of eqe and aeqe ensures that the valid
bit and queue number read by the CPU were written by the device
simultaneously.
