mlx5: avoid 64-bit division in dr_icm_pool_mr_create()
Recently added code introduces 64-bit division in dr_icm_pool_mr_create()
so that build on 32-bit architectures fails with
ERROR: "__umoddi3" [drivers/net/ethernet/mellanox/mlx5/core/mlx5_core.ko] undefined!
As the divisor is always a power of 2, we can use bitwise operation
instead.
Fixes: 29cf8febd185 ("net/mlx5: DR, ICM pool memory allocator")
