RDMA/i40iw: Fix incorrect iterator type
[ Upstream commit 802fa45cd320de319e86c93bca72abec028ba059 ]
Commit f27b4746f378 ("i40iw: add connection management code") uses an
incorrect rcu iterator, whilst holding the rtnl_lock. Since the
critical region invokes i40iw_manage_qhash(), which is a sleeping
function, the rcu locking and traversal cannot be used.
