Sergey Senozhatsky cb0551adf9 zram: further limit recompression threshold
Recompression threshold should be below huge-size-class watermark.  Any
object larger than huge-size-class is a "huge object" and occupies a
whole physical page on the zsmalloc side, in other words it's
incompressible, as far as zsmalloc is concerned.
