md: Revert "md: Fix overflow in is_mddev_idle"
This reverts commit 3f9f231236ce7e48780d8a4f1f8cb9fae2df1e4e.
Using 64bit for 'sync_io' is unnecessary from the gendisk side. This
overflow will not cause any functional impact, except for a UBSAN
warning. Solving this overflow requires introducing additional
calculations and checks which are not necessary. So just keep using
32bit for 'sync_io'.
