Subject[PATCH 4.19 257/321] RDMA/hns: Fix the state of rereg mr
Date
From: Yixian Liu <liuyixian@huawei.com>

[ Upstream commit ab22bf05216a6bb4812448f3a8609489047cf311 ]

The state of mr after reregister operation should be set to valid
state. Otherwise, it will keep the same as the state before reregistered.
