md/raid5: set reshape_position correctly when reshape starts.
NeilBrown [Mon, 3 Aug 2009 00:59:57 +0000 (10:59 +1000)]
As the internal reshape_progress counter is the main driver
for reshape, the fact that reshape_position sometimes starts with the
wrong value has minimal effect.  It is visible in sysfs and that
is all.
