KVM: x86/xen: ignore the VCPU_SSHOTTMR_future flag

Browse source

Upstream Xen now ignores _VCPU_SSHOTTMR_future[1], since the only guest
kernel ever to use it was buggy. By ignoring the flag the guest will
always get a callback if it sets a negative timeout which upstream Xen
has determined not to cause problems for any guest setting the flag.
