RDMA/addr: Fix some cancellation problems in process_req()
Fix following problems in process_req() relating to cancellation: - Function is wrongly doing another addr_remote() when cancelled, which is not required. - Make failure reporting immediate by using time_after_eq(). - On cancellation, -ETIMEDOUT was returned to the callback routine instead of the more appropriate -ECANCELLED (users getting notified may want to print/return this status, eg ucma_event_handler).
