net: hns3: Fix client initialize state issue when roce client initialize failed

[ Upstream commit d9f28fc2 ]

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.
