[GPOS] Fix assert fail introduced recently Was introduced in 8708b9e081192786c027bb7f5f23d76dbe5c19e8. If these lookups are recursed to from (Chain)Context out-of-order, it was possible that last_base > buffer->idx, in which case we were attaching marks to a base after them... and an assertion was failing fortunately.
