x86: Fix broken LDT access in VMI
After investigating a JRE failure, I found this bug was introduced a
long time ago, and had already managed to survive another bugfix which
occurred on the same line. The result is a total failure of the JRE due
to LDT selectors not working properly.
This one took a long time to rear up because LDT usage is not very
common, but the bug is quite serious. It got introduced along with
another bug, already fixed, by 75b8bb3e56ca09a467fbbe5229bc68627f7445be
