RDMA/hns: Support adaptive PBL hopnum

Browse source

In the current implementation, a fixed addressing level is used for
PBL. But in fact, the necessary addressing level is related to page
size and the size of MR.

This patch calculates the addressing level according to page size
and the size of MR, and uses the addressing level to configure the
PBL.
