In some situations we can receive the ORB status write before we
have received the ORB pointer write response.  When this happens,
we assume that the fw_transaction is finished and free the ORB
struct containing the fw_transaction.

This fix make the status write logic only accept status writes
for ORBs where the initial ORB pointer write transaction finished.

Some devices have a really long power-on cycle, and we fail to
successfully probe these if they're plugged in and then turned on.

There's really no down-side to bumping the number of retries and the
retry delay, and most devices will get picked up within the first couple
of retries anyway.

In case the topology build fails, we want to retain the old topology
info until another reset finishes and results in a valid new tree.  If
we clear card->irm_node to NULL and the topology build fails, we end up
dereferencing a NULL pointer in a few places.
