RDMA/hns: Fix wrong timer context buffer page size
The HEM page size for QPC timer and CQC timer is always 4K and there's no
need to calculate a different size by the hns driver, otherwise the ROCEE
may access an invalid address.
Fixes: 719d13415f59 ("RDMA/hns: Remove duplicated hem page size config code")
