    dav: Prevent usage of uninitialized variable
    
    More warnings are printed when building thanks to meson port. The mounting
    loop may be breaked before is_webdav variable is defined. Let's move the
    initialization to another place in order to prevent usage of uninitialized
    variable and the following warning:
    warning: ‘is_webdav’ may be used uninitialized in this function
