    x86/hvm: Partially revert ("xen/mem_access: wrap memory access when 
VM_EVENT=n")
    
    It is erroneous to check current like this; most commonly, introspection is
    dom0 issuing hypercalls against domU.
    
    The use of vm_event_is_enabled() is only for the IS_ENABLED(CONFIG_VM_EVENT)
    short circut, so just use that directly.
