[PATCH] crypto: hisilicon/qm - remove unneeded hardware cache write back

[Yang Shen]

From: Weili Qian <qianweili@xxxxxxxxxx>

Data in the hardware cache needs to be written back to the memory
before the queue memory is released. Currently, the queue memory is
applied for when the driver is loaded and released when the driver is
removed. Therefore, the hardware cache does not need to be written back
when process puts queue.
