[PATCH] xsave: export get_xsave_addr

[Tiejun Chen <tiejun.chen@intel.com>]

After commit, 1d7fe1d1, "KVM: x86: support XSAVES usage in the host",
is introduced,

  ...
  Building modules, stage 2.
  MODPOST 20 modules
ERROR: "get_xsave_addr" [arch/x86/kvm/kvm.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2

so we need to export get_xsave_addr() while using KVM as
a module.

I'm not sure if this is already fixed so just post in advance.
