VMM/HMVMXR0: Update comment and add assertion. We no longer have gaps between leaving and thread-context hook deregisteration.

trunk/src/VBox/VMM/VMMR0/HMVMXR0.cpp

     /*
-     * The VMCS state here will not be reliable because we deregister the hook in VMMR0EntryFast()
-     * on the way out. If we had got a preempt/resume callback -after- hmR0VmxLeave() but before
-     * deregistering the hook, the VMCS state will be ACTIVE. Once deregistered we no longer get
-     * notifications and lose track. Following that if we get rescheduled to another host CPU, the
-     * VMCS state says ACTIVE even though it really is not.
+     *
      * Load the VCPU's VMCS as the current (and active) one.
