Subject: [PATCH] crypto: algif_skcipher - Cap recv SG list at ctx->used
Somewhere along the line the cap on the SG list length for receive
was lost. This patch restores it and removes the subsequent test
which is now redundant.

We don't have 2d97591ef43d ("crypto: af_alg - consolidation of duplicate
code") in our 4.9 and 4.4 trees.
We do carry an "out of tree" backport that fixes an issue silently fixed
by 2d97591ef43d, but it does not introduce the issue that this patch
fixes.
