Fix unused-but-set-variable compiler warning in reorderbuffer.c.

Browse Source 
On v13, this variable is only used for an assertion, so adding
PG_USED_FOR_ASSERTS_ONLY is sufficient to suppress this warning on
builds with assertions disabled.  Older versions are unsupported,
and newer versions use the variable for more than the assertion, so
this patch only needs to be applied to REL_13_STABLE.
