crypto/mlx5: add WQE set initialization

Currently, HW handles the WQEs much faster than the software,
Using the constant WQE set layout can initialize most of the WQE
segments in advanced, and software only needs to configure very
limited segments in datapath. This accelerates the software WQE
organize in datapath.

This commit initializes the fixed WQE set segments.
