md: fix sync_completed reporting for very large drives (>2TB)
The values exported in the sync_completed file are unsigned long, which
overflows with very large drives, resulting in wrong values reported.
Since sync_completed uses sectors as unit, we'll start getting wrong
values with components larger than 2TB.
This patch simply replaces the use of unsigned long by unsigned long long.
