IB/cm: Store and restore ah_attr during LAP msg processing

Browse source

During CM LAP processing, ah_attr is reinitialized on receiving LAP
request. First likely during CM request processing.

ah_attr might get zero out if LAP processing fails.
Therefore, attempt to create new ah_attr for the LAP message.
If the initialization fails, continue with older ah_attr.
If the initialization passes, consider the new ah_attr by overwriting
the older one.
