crypto: hisilicon/qm - invalidate queues in use

Browse source

[ Upstream commit 85acd1b26b ]

Before the device reset, although the driver has set the queue
status to intercept doorbells sent by the task process, the reset
thread is isolated from the user-mode task process, so the task process
may still send doorbells. Therefore, before the reset, the queue is
directly invalidated, and the device directly discards the doorbells
sent by the process.
