    kallsyms: Make module_kallsyms_on_each_symbol generally available
    
    commit 73feb8d5fa3b755bb51077c0aabfb6aa556fd498 upstream.
    
    Making module_kallsyms_on_each_symbol generally available, so it
    can be used outside CONFIG_LIVEPATCH option in following changes.
    
    Rather than adding another ifdef option let's make the function
    generally available (when CONFIG_KALLSYMS and CONFIG_MODULES
    options are defined).
