The AR req handler should not check the generation; higher level code
is the better place to handle bus generation changes. The target node
ID just needs to be checked for not being the "all nodes" address; in
this case don't handle the request and don't respond.
Use Address_Error and Type_Error rcodes as appropriate.

Fix some problems from "firewire: net: allow for unordered unit
discovery":
- fwnet_remove was missing a list_del, causing fwnet_probe to crash if
called after fwnet_remove, e.g. if firewire-ohci was unloaded and
reloaded.
- fwnet_probe should set its new_netdev flag only if it actually
allocated a net_device.
- Use dev_set_drvdata and dev_get_drvdata instead of deprecated direct
access to device.driver_data.

The .ndo_tx_timeout callback is currently without function; delete it.
Give .watchdog_timeo a proper time value; lower it to 2 seconds.
Decrease the .tx_queue_len from 1000 (as in Ethernet card drivers) to 10
because we have only 64 transaction labels available, and responders
might have further limits of their AR req contexts.

Decouple the creation and destruction of the net_device from the order
of discovery and removal of nodes with RFC 2734 unit directories since
there is no reliable order. The net_device is now created when the
first RFC 2734 unit on a card is discovered, and destroyed when the last
RFC 2734 unit on a card went away. This includes all remote units as
well as the local unit, which is therefore tracked as a peer now too.
Also, locking around the list of peers is slightly extended to guard
against peer removal. As a side effect, fwnet_peer.pdg_lock has become
superfluous and is deleted.
Peer data (max_rec, speed, node ID, generation) are updated more
carefully.

The driver is now called firewire-net. It might implement the transport
of other networking protocols in the future, notably IPv6 per RFC 3146.
