[PATCH] gostr3411-94: fix the iteration count for length filling loop

[Dmitry Eremin-Solenikov]

The maximum iteration count for filling the l (bit length) array was
incrrectly set to 32 (missed that in u8->u32 refactoring). This was not
resulting in stack corruption, since nblocks variable would be exausted
earlier compared to 8 32-bit values (the size of the array).
