[PATCH 4.4 122/192] [PATCH 126/135] crypto: vmx - IV size failing on skcipher API

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 0d3d054b43719ef33232677ba27ba6097afdafbc ]

IV size was zero on CBC and CTR modes,
causing a bug triggered by skcipher.

Fixing this  adding a correct size.
