    mtp: Fix mounting for devices with special chars in ID_SERIAL
    
    ID_SERIAL string is not URI-escaped before use, but unfortunatelly, it
    may contain special characters (e.g. colons) and consequently it is not
    possible to mount affected devices over activation_root. Let's URI-escape
    the ID_SERIAL string before use as URI to fix that issue.
