From: Aharon Landau <aharonl@nvidia.com>

mkc.log_page_size can be changed using UMR. Therefore, don't treat it as
a cache entry property.
Removing it from struct mlx5_cache_ent.
All cache mkeys will be created with default PAGE_SHIFT, and updated
with the needed page_shift using UMR when passing them to a user.
