Subject: RDMA/hns: Enable inner_pa_vld filed of mpt
Patch-mainline: v4.17-rc7
Git-commit: 85e0274dc66430b0d0fad7ad01cbc0e0cbebf6dc
References: bsc#1104427 FATE#326416
When enabled inner_pa_vld field of mpt, The pa0 and
pa1 will be valid and the hardware will use it
directly and not use base address of pbl. As a
result, it can reduce the delay.
