md/raid5: make sure curr_sync_completes is uptodate when reshape starts
commit 8dee7211467a56b7eb4e4359efb0aa4a72e1b6f3 upstream.
This value is visible through sysfs and is used by mdadm
when it manages a reshape (backing up data that is about to be
rearranged). So it is important that it is always correct.
Current it does not get updated properly when a reshape
starts which can cause problems when assembling an array
that is in the middle of being reshaped.
This is suitable for 2.6.31.y stable kernels.
