Li Zhong 901d3d4fee crypto: vmx - fix null dereference in p8_aes_xts_crypt 
walk.iv is not assigned a value in blkcipher_walk_init. It makes iv uninitialized.
It is possibly a null value(as shown below), which is then used by aes_p8_encrypt.

This patch moves iv = walk.iv after blkcipher_walk_virt, in which walk.iv is set.
