RDMA/hns: Fix an AEQE overflow error caused by untimely update of eq_db_ci
eq_db_ci is updated only after all AEQEs are processed in the AEQ
interrupt handler, which is not timely enough and may result in
AEQ overflow. Two optimization methods are proposed:
1. Set an upper limit for AEQE processing.
2. Move time-consuming operations such as printings to the bottom
half of the interrupt.
cmd events and flush_cqe events are still fully processed in the top half
to ensure timely handling.
