[PATCH] xen: Fix incorrect taint constant

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Insecure the word being looked for here.  Especially given the nature of the
sole caller, and the (correct) comment next to it.

I've left the taint constant as 'U' as it's a rather more user-visible.

Fixes: 82c0d3d491cc ("xen: Add an unsecure Taint type")

I'm happy to change 'U' to 'I' if we think that no-one is going to be impacted
by it.  I just wasn't sure.
