The same result could be obtained as follows:

float projinv[4][4];
invert_m4_m4(projinv, projmat);
co[0] = 2 * co[0] - 1;
co[1] = 2 * co[1] - 1;
co[2] = 2 * co[2] - 1;
mul_project_m4_v3(projinv, co);

But that solution loses much precision. Therefore, get the same result without inverting the matrix.
