md: fix data corruption for raid456 when reshape restart while grow up
Currently, if reshape is interrupted, echo "reshape" to sync_action will
restart reshape from scratch, for example:
echo frozen > sync_action
echo reshape > sync_action
This will corrupt data before reshape_position if the array is growing,
fix the problem by continue reshape from reshape_position.
