sufficient to clobber this nasty little bug. The behaviour observed
was a panic when doing a 'raidctl -f' on a component when DAGs were
in flight for the given RAID set. Unfortunatly, the faulty behaviour
was very intermittent, and it was difficult to not only reliably
reproduce the bug (nor determine when it was fixed!) but also to even
figure out what might be the cause of the problem.
The real issue was that ci_vp for the failed component was being
set to NULL in rf_FailDisk(), but with DAGs still in flight, some
of them were still expecting to use ci_vp to determine where to
read to/write from!
The fix is to call rf_SuspendNewRequestsAndWait() from rf_FailDisk()
to make sure the RAID set is quiet and all IOs have completed before
mucking with ci_vp and other data structures. rf_ResumeNewRequests()
is then used to continue on as usual.
finding an ffsv1 sb at 64k.
Also stop it playing with fs that have 'FS_FLAGS_UPDATED' set.
It certainly doesn't act on that falg, and my guess is that it is
playing the pre-ffsv2 fs.

Ensure that we don't use the first alternate superblock of a ffsv1
filesystem with 64k blocks (it is in the same place as an ffsv2 sb).
