The function get_fd extract context from the received MAD message and uses it as a key to fetch the destination fd from the mapping table. A context can be dgid in case of CM request message or comm_id in case of CM SIDR response message. When MAD message with a smaller size as expected for the message type received we are hitting out-of-bounds where we are looking for the context out of message boundaries. Fix it by validating the message size.
