RDMA/hns: Remove the num_qpc_timer variable
The bt number of qpc_timer of HIP09 increases compared with that of HIP08.
Therefore, qpc_timer_bt_num and num_qpc_timer do not match. As a result,
the driver may fail to allocate qpc_timer. So the driver needs to uniquely
uses qpc_timer_bt_num to represent the bt number of qpc_timer.
Fixes: 0e40dc2f70cd ("RDMA/hns: Add timer allocation support for hip08")
