[ Upstream commit 12cb3a1c4184f891d965d1f39f8cfcc9ef617647 ]

Since the    commit f1c131b45410a202eb45cc55980a7a9e4e4b4f40    crypto: xts - Convert to skcipher

That commit went into 4.10, and not any stable branches. So this fix doesn't appear to be appropriate for the older branches it was applied to.

Ben.

the XTS mode is based on ECB, so the mode must select ECB otherwise it can fail to initialize.
