Rework vmx_set_rflags() to avoid the extra code need to handle emulation of real mode and invalid state when unrestricted guest is disabled. The primary reason for doing so is to avoid the call to vmx_get_rflags(), which will incur a VMREAD when RFLAGS is not already available. When running nested VMs, the majority of calls to vmx_set_rflags() will occur without an associated vmx_get_rflags(), i.e. when stuffing GUEST_RFLAGS during transitions between vmcs01 and vmcs02. Note, vmx_get_rflags() guarantees RFLAGS is marked available.
