NeilBrown af3a2cd6b8 md: Fix read balancing in RAID1 and RAID10 on drives > 2TB ...

read_balance uses a "unsigned long" for a sector number which
will get truncated beyond 2TB.
This will cause read-balancing to be non-optimal, and can cause
data to be read from the 'wrong' branch during a resync.  This has a
very small chance of returning wrong data.
