RDMA/hns: Fix the double unlock problem of poll_sem If hns_roce_cmd_use_events() fails then it means that the poll_sem is not obtained, but the poll_sem is released in hns_roce_cmd_use_polling(), this will cause an unlock problem. This is the static checker warning: drivers/infiniband/hw/hns/hns_roce_main.c:926 hns_roce_init() error: double unlocked '&hr_dev->cmd.poll_sem' (orig line 879) Event mode and polling mode are mutually exclusive and resources are separated, so there is no need to process polling mode resources in event mode. The initial mode of cmd is polling mode, so even if cmd fails to switch to event mode, it is not necessary to switch to polling mode.

RDMA/hns: Optimize cmd init and mode selection for hip08 There are two modes for mailbox command (cmd) queue, i.e., event mode and poll mode. For each mode, we use corresponding semaphores to protect the cmd queue resource competition, so called event_sem and poll_sem. During cmd init, both semaphores are initialized and poll mode is selected. Thus, there is no need to up poll_sema again in cmd_use_polling. Furthermore, there is no need to down the sema of the other side while switching mode. This patch aims to decouple the switch between event mode and poll mode of cmd.
