math/big: fix a formula used as documentation
The function documentation was wrong, it was using a wrong parameter. This change
replaces it with the right parameter.
The wrong formula was: q = (u1<<_W + u0 - r)/y
The function has got a parameter "v" (of type Word), not a parameter "y".
So, the right formula is: q = (u1<<_W + u0 - r)/v
Fixes #28444
