crypto: hisilicon/sec - move backlog management to qp and store sqe in qp for callback
[ Upstream commit 08eb67d23e5172a5d1e60f1f0acccee569fe10ba ]
When multiple tfm use a same qp, the backlog data should be managed
centrally by the qp, rather than in the qp_ctx of each req.
Additionally, since SEC_BD_TYPE1 and SEC_BD_TYPE2 cannot use the
tag of the sqe to carry the virtual address of the req, the sent
sqe is stored in the qp. This allows the callback function to get
the req address. To handle the differences between hardware types,
the callback functions are split into two separate implementations.
Fixes: f0ae287c5045 ("crypto: hisilicon/sec2 - implement full backlog mode for sec")
