libhns: Reimplement verbs of post_send and post_recv for hip08 RoCE

The verbs of post_send and post recv need to fill sqwqe and rqwqe and issue the doorbell cmd. The sqwqe&rqwqe&doorbell structures are different between hip06 and hip08 etc. Hence, It needs to rewrite the verbs of post_send and post_recv.
