[PATCH] KVM: VMX: Use wrapper macro ~RMODE_GUEST_OWNED_EFLAGS_BITS directly

[linmiaohe]

From: Miaohe Lin <linmiaohe@xxxxxxxxxx>

(X86_EFLAGS_IOPL | X86_EFLAGS_VM) indicates the eflag bits that can not be
owned by realmode guest, i.e. ~RMODE_GUEST_OWNED_EFLAGS_BITS. Use wrapper
macro directly to make it clear and also improve readability.
