Ondrej Mosnacek c2ff394968 crypto: lrw - Fix out-of bounds access on counter overflow 
commit fbe1a850b3 upstream.

When the LRW block counter overflows, the current implementation returns
128 as the index to the precomputed multiplication table, which has 128
entries. This patch fixes it to return the correct value (127).

Fixes: 64470f1b85 ("[CRYPTO] lrw: Liskov Rivest Wagner, a tweakable narrow block cipher mode")
