RDMA/{cma, core}: Avoid callback on rdma_addr_cancel()
Currently rdma_addr_cancel() is an async operation, which notifies that cancel is done by executing the callback function given during rdma_resolve_ip(). If resolve_ip request is already completed than callback is not executed. Instead, now rdma_resolve_addr() and rdma_addr_cancel() simplified in following ways. 1. rdma_addr_cancel() now a synchronous method. If request was pending, after it is cancelled, no callback is notified. 2. rdma_resolve_addr() and respective addr_handler() callback doesn't need to hold reference to cm_id.
