[ Upstream commit d9f28fc23d544f673d087b00a6c7132d972f89ea ]
When roce is loaded before nic, the roce client will not be initialized until nic client is initialized, but roce init flag is set before it. Furthermore, in this case of nic initialized success and roce failed, the nic init flag is not set, and roce init flag is not cleared.
This patch fixes it by set init flag only after the client is initialized successfully.
