RDMA/hns: Fix wrong timer context buffer page size

Browse Source 
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: 719d13415f ("RDMA/hns: Remove duplicated hem page size config code")
