x86/kvm: Avoid looking up PKRU in XSAVE buffer
PKRU is being removed from the kernel XSAVE/FPU buffers. This removal
will probably include warnings for code that look up PKRU in those
buffers.
KVM currently looks up the location of PKRU but doesn't even use the
pointer that it gets back. Rework the code to avoid calling
get_xsave_addr() except in cases where its result is actually used.
This makes the code more clear and also avoids the inevitable PKRU
warnings.
This is probably a good cleanup and could go upstream idependently
of any PKRU rework.
