Fix SkMatrix44::invert(...) for identity matrices and a NULL parameter
Currently, to check if an SkMatrix44 is singular, we call ::invert(NULL) and
check the result. Usually this does no more work than is necessary. One
case where we do far too much work is if |this| is an identity matrix. In
this case, we do not early out and compute a (partial) determinant (we don't
do the full shebang because there are no perspective components).
