[Milan Crha <mcrha src gnome org>]

commit e3e1f8c19d347374e6e42cc10729ede38a91b29d

    packagekit: Set download size to 0 after the package is downloaded
    
    Once the package is downloaded there is no additional data to be downloaded,
    thus reset the download size to zero. This is also used to recognize whether
    the application is downloaded or not.
