When AF_IB addresses are used during rdma_resolve_addr(), currently lock
is not held. A cma device can get removed while such list traversal is
in progress which may lead to crash.
Therefore, hold a lock while traversing the list which avoids such
situation.
This patch doesn't come as an outcome of real crash, but from code review.
