Fix incorrect math in DetermineSafeOldestOffset.

The old formula didn't have enough parentheses, so it would do the wrong
thing, and it used / rather than % to find a remainder.  The effect of
these oversights is that the stop point chosen by the logic introduced in
commit b69bf30b9bfacafc733a9ba77c9587cf54d06c0c might be rather
meaningless.

Thomas Munro, reviewed by Kevin Grittner, with a whitespace tweak by me.
