ieee1394: run high-level updates before high-level probes
After a bus reset, let nodemgr call high-level update hooks first for nodes
which do not need to be probed. The main benefit is for a bus with more
than one SBP-2 device: SBP-2 reconnects will be performed before SBP-2
logins, thus have a much higher chance to succeed, and their SCSI devices
will not be blocked much longer than necessary. This was demonstrated for
Linux 2.4 by Dave Cinege a while ago.
A better approach would be to perform time-consuming probes in parallel by a
subthread. I actually plan to implement this for sbp2 but it may take a
while to get that done and tested. Until then, this tweak is a huge
improvement for users with multiple SBP-2 devices.
