When a client is added it isn't allowed to fail, but all the client's have
various failure paths within their add routines.
This creates the very fringe condition where the client was added, failed
during add and didn't set the client_data. The core code will then still
call other client_data centric ops like remove(), rename(), get_nl_info(),
and get_net_dev_by_params() with NULL client_data - which is confusing and
unexpected.
If the add() callback fails, then do not call any more client ops for the
device, even remove.
Remove all the now redundant checks for NULL client_data in ops callbacks.
Update all the add() callbacks to return error codes
appropriately. EOPNOTSUPP is used for cases where the ULP does not support
the ib_device - eg because it only works with IB.

The default version provided by "ethtool -i" it the correct way
to identify Driver version. There is no need to overwrite it.

Introduce a 'flags' field to destroy address handle callback and add a
flag that marks whether the callback is executed in an atomic context or
not.
This will allow drivers to wait for completion instead of polling for it
when it is allowed.

The functions ib_register_event_handler() and
ib_unregister_event_handler() always returned success and they can't fail.
Let's convert those functions to be void, remove redundant checks and
cleanup tons of goto statements.

rdma_ah_attr can now be either ib or roce allowing
core components to use one type or the other and also
to define attributes unique to a specific type. struct
ib_ah is also initialized with the type when its first
created. This ensures that calls such as modify_ah
dont modify the type of the address handle attribute.

OPA VEMA function interfaces with the Infiniband MAD stack to exchange the
management information packets with the Ethernet Manager (EM).
It interfaces with the OPA VNIC netdev function to SET/GET the management
information. The information exchanged with the EM includes class port
details, encapsulation configuration, various counters, unicast and
multicast MAC list and the MAC table. It also supports sending traps
to the EM.
