crypto: hisilicon/qm - add reference counting to queues for tfm kernel reuse

Browse source

Add reference counting to queues. When all queues are occupied, tfm
will reuse queues with the same algorithm type that have already
been allocated in the kernel. The corresponding queue will be
released when the reference count reaches 1.
