[PATCH 18/20] x86/uapi: Do not export <asm/msr-index.h> as part of the user API headers

[Borislav Petkov <bp@alien8.de>]

From: Borislav Petkov <bp@suse.de>

This header containing all MSRs and respective bit definitions got
exported to userspace in conjunction with the big UAPI shuffle.

But, it doesn't belong in the UAPI headers because userspace can do
its own MSR defines and exporting them from the kernel blocks us from
doing cleanups/renames in that header. Which is ridiculous - it is not
kernel's job to export such a header and keep MSRs list and their names
stable.
