Subject: RDMA/hns: Modify ba page size for cqe
Patch-mainline: v5.3-rc1
Git-commit: f5662b4ddc9db20033f310694edbd3fc7041f6f2
References: bsc#1104427 FATE#326416

Currently, the depth of cq only supports 64K.  According to the UM, the
depth of cq is up to 4M, Therefore the ba page size of cqe was modified to
support the maximum specification of cq depth.
