KVM: x86: do not save guest-unsupported XSAVE state
commit 00c87e9a70a17b355b81c36adedf05e84f54e10d upstream.
Saving unsupported state prevents migration when the new host does not
support a XSAVE feature of the original host, even if the feature is not
exposed to the guest.
We've masked host features with guest-visible features before, with
4344ee981e21 ("KVM: x86: only copy XSAVE state for the supported
features") and dropped it when implementing XSAVES. Do it again.
Fixes: df1daba7d1cb ("KVM: x86: support XSAVES usage in the host")
