crypto: algif_skcipher - Require setkey before accept(2)
commit dd504589577d8e8e70f51f997ad487a4cb6c026f upstream.
Some cipher implementations will crash if you try to use them
without calling setkey first. This patch adds a check so that
the accept(2) call will fail with -ENOKEY if setkey hasn't been
done on the socket yet.
