KVM: MMU: split reset_rsvds_bits_mask_ept
Since shadow ept page tables and Intel nested guest page tables have the same format, split reset_rsvds_bits_mask_ept so that the logic can be reused by later patches which check zero bits on sptes Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
