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.
