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.
