[glib: 13/30] gatomic: Drop unnecessary volatile qualifiers from internal variables

[Philip Withnall <pwithnall src gnome org>]

commit 3c648457c284b4ba313b8591008d2e18ae4335eb

    gatomic: Drop unnecessary volatile qualifiers from internal variables
    
    It’s not necessary and provides no thread safety guarantees.
    
    The `volatile` qualifiers on the function arguments have to be kept, as
    they are (unfortunately) part of the API.
