crypto: hisilicon/hpre: extend tag field to 64 bits for better performance

Browse source

[ Upstream commit 3a19847581 ]

This commit expands the tag field in hpre_sqe structure from 16-bit
to 64-bit. The change enables storing request addresses directly
in the tag field, allowing callback functions to access request messages
without the previous indirection mechanism.

By eliminating the need for lookup tables, this modification reduces lock
contention and associated overhead, leading to improved efficiency and
simplified code.
