Description:
geom_raid3 is not rebuilding stale components. Removing/inserting, using "graid3
rebuild", etc. commands doesn't help. Syslog shows that rebuild has started, but
the synchronized value stays at 0%:
GEOM_RAID3: Device 0: provider ad12 detected. GEOM_RAID3: Device 0: rebuilding provider ad12.

How-To-Repeat:
Build a new graid3 array (perhaps using md devices), remove one component, then
insert it again. Rebuild appears to start, but monitoring with "gstat" shows no
real activity. Output of "graid3 list" or "graid3 status" shows 0%.
Fix:
Revert to rev 1.40.2.12 of src/sys/geom/raid3/g_raid3.c. This problematic change
was apparently MFC'd on Sept 4th.
