Subject: zswap: init under_reclaim

Bob Liu reported a memory leak in zswap.  This was due to the
under_reclaim field in the zbud header not being initialized
to 0, which resulted in zbud_free() not freeing the page
under the false assumption that the page was undergoing
zbud reclaim.

This patch properly initializes the under_reclaim field.
