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

Fixing this  adding a correct size.

AES-CTR is using a counter 8bytes-8bytes what miss match with
kernel specs.

In the previous code a vadduwm was done to increment counter.
Replacing this for a vadduqm now considering both cases counter
8-8 bytes and full 16bytes.

vmx-crypto driver make use of some VSX instructions which are
only available if VSX is enabled. Running in cases where VSX
are not enabled vmx-crypto fails in a VSX exception.

In order to fix this enable_kernel_vsx() was added to turn on
VSX instructions for vmx-crypto.
