[gtksourceview: 3/3] Bracket matching: fix FIXME about iter sometimes uninitialized

[Sébastien Wilmet <swilmet src gnome org>]

    Bracket matching: fix FIXME about iter sometimes uninitialized
    
    priv->bracket_match is not equal to FOUND, so the parameter is
    meaningless, so it's more logical to provide NULL.
