    pango: Remove some unnecessary NULL checks
    
    These checks are preceded by other checks or code which demonstrates
    that the values are definitely always non-NULL.
    
    In the case of pango_attr_list_insert_internal(), the final branch of
    the function never needs to update list->attributes_tail, as the middle
    branch handles the case of appending to the list. The final case is just
    for insertions in the middle of the list.
