Revert "x86/entry/64: Add missing irqflags tracing to native_load_gs_index()"

This reverts commit f9a64e23a9da528e7d8aa1bd2c7bb92be4ebb724 which is
commit 0d794d0d018f23fb09c50f6ae26868bd6ae343d6 upstream.

Andy writes:

I think the thing to do is to revert the patch from -stable.
The bug it fixes is very minor, and the regression is that it
made a pre-existing bug in some nearly-undebuggable core resume
code much easier to hit.  I don't feel comfortable with a
backport of the latter fix until it has a good long soak in
Linus' tree.
