RDMA/bnxt_re: consider timeout of destroy ah as success. If destroy_ah is timed out, it is likely to be destroyed by firmware but it is taking longer time due to temporary slowness in processing the rcfw command. In worst case, there might be AH resource leak in firmware. Sending timeout return value can dump warning message from ib_core which can be avoided if we map timeout of destroy_ah as success.
