Revert "lzo: properly check for overruns"

commit af958a38a60c7ca3d8a39c918c1baa2ff7b6b233 upstream.

This reverts commit 206a81c ("lzo: properly check for overruns").

As analysed by Willem Pinckaers, this fix is still incomplete on
certain rare corner cases, and it is easier to restart from the
original code.
