[PATCH v4 04/11] crypto: hisilicon/qm - enhance the configuration of req_type in queue attributes

[Chenghai Huang <huangchenghai2@huawei.com>]

Originally, when a queue was requested, it could only be configured
with the default algorithm type of 0. Now, when multiple tfms use
the same queue, the queue must be selected based on its attributes
to meet the requirements of tfm tasks. So the algorithm type
attribute of queue need to be distinguished. Just like a queue used
for compression in ZIP cannot be used for decompression tasks.

Fixes: 3f1ec97aacf1 ("crypto: hisilicon/qm - Put device finding logic into QM")
