x86/vmx: don't call __vmxoff() blindly

If vmx_vcpu_up() failed, __vmxon() would generally not have got
(successfully) executed, and in that case __vmxoff() will #UD.

Additionally, any panic() during early resume (namely the tboot
related one) would cause vmx_cpu_down() to get executed without
vmx_cpu_up() having run before.
