crypto: hisilicon/qm - remove redundant cache writeback

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4W3OQ



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

Currently, the memory of the queue's sqe is freed when
the driver is removed, not the put queue. Therefore, it is only
necessary to write back the data in the hardware cache to
memory before removing the driver.
