Subject: [PATCH] RDMA/hns: Fix to support 64K page for srq
commit 5c7e76fb7cb5071be800c938ebf2c475e140d3f0 upstream.
SRQ's page size configuration of BA and buffer should depend on current
PAGE_SHIFT, or it can't work in scenario of 64K page.
Fixes: c7bcb13442e1 ("RDMA/hns: Add SRQ support for hip08 kernel mode")
