target/i386: sev: Remove redundant policy field

Browse source 
SEVState::policy is set from the final value of the policy field in the
parameter structure for the KVM_SEV_LAUNCH_START ioctl().  But, AFAICT
that ioctl() won't ever change it from the original supplied value which
comes from SevGuestState::policy.

So, remove this field and just use SevGuestState::policy directly.
