#6778: [with patch, needs review] Fix nfacets for non-reflexive lattice
polytopes

----------------------+-----------------------------------------------------
There is a silly bug in computing the number of facets of non-reflexive
lattice polytopes:
{{{
sage: p = LatticePolytope(matrix([1, 2]))
sage: p.nfacets()
Traceback (most recent call last):
...
TypeError: object of type
'sage.matrix.matrix_integer_dense.Matrix_integer_dense' has no len()
}}}
The attached one-line patch fixes it:
{{{
sage: p = LatticePolytope(matrix([1, 2]))
sage: p.nfacets()
2
}}}
