The iWARP connection manager uses the ib_addr services to do route
resolution (neighbour discovery in the IP world). The ib_addr
netevent callback routine, however, currently only acts on InfiniBand
neighbour updates. It needs to act on ethernet neighbour updates as
well.
This patch just removes filtering on device type altogether and will
trigger on any neighour updates where the nud_type is valid. This
simplifies the code some.

Fix following problems in process_req() relating to cancellation:
- Function is wrongly doing another addr_remote() when cancelled,
which is not required.
- Make failure reporting immediate by using time_after_eq().
- On cancellation, -ETIMEDOUT was returned to the callback routine
instead of the more appropriate -ECANCELLED (users getting notified
may want to print/return this status, eg ucma_event_handler).

In queue_req(), use time_after_eq() instead of time_after()
for following reasons :
- Improves insert time if multiple entries with same time are
present.
- set_timeout need not be called if entry with same time
is added to the list (and that happens to be the entry
with the smallest time), saving atomic/locking operations.
- Earlier entries with same time are deleted first (fifo).

Modifications to the existing rdma header files, core files, drivers,
and ulp files to support iWARP, including:
- Hook iWARP CM into the build system and use it in rdma_cm.
- Convert enum ib_node_type to enum rdma_node_type, which includes
the possibility of RDMA_NODE_RNIC, and update everything for this.
