Observe array length in HaveVirtualXIDsDelayingChkpt().

Browse Source 
Since commit f21bb9cfb5, this function
ignores the caller-provided length and loops until it finds a
terminator, which GetVirtualXIDsDelayingChkpt() never adds.  Restore the
previous loop control logic.  In passing, revert the addition of an
unused variable by the same commit, presumably a debugging relic.
