pivot-table: Properly allocate pivot_table's current_layer.

The default current_layer should be all-zeros, but the code wasn't
allocating current_layer at all.  This didn't cause much of a problem
because nothing in the current tree allocates layers, but it will as
layers are added.

Thanks to John Darrington for reporting the bug.
