math/big: fix out-of-bounds panic in divRecursive
The bounds in the last carry branch were wrong as there
is no reason for len(u) >= n+n/2 to always hold true.
We also adjust test to avoid using a remainder of 1
(in which case, the last step of the algorithm computes
(qhatv+1) - qhatv which rarely produces a carry).
