x86/HVM: fix failure path in hvm_vcpu_initialise

It looks like one of the failure cases in hvm_vcpu_initialise jumps to
the wrong label; this could lead to slow leaks if something isn't
cleaned up properly.

I will probably change these labels in a future patch, but I figured
it was better to have this fix separately.

This is also a candidate for backport.
