    gdb: add missing prepare_reinflate call in print_frame_info
    
    print_frame_info calls frame_info_ptr::reinflate, but not
    frame_info_ptr::prepare_reinflate, add the call to prepare_reinflate.
    It works right now, because all callers of print_frame_info that could
    possibly lead to the pretty printers being called, and the frame_info
    objects being invalidated, do call prepare_reinflate themselves.  And
    since the cached frame id is copied when passing a frame_info_ptr by
    value, print_frame_info does have a cached frame id on entry.  So
    technically, this change isn't needed.  But I don't think it's good for
    a function to rely on its callers to have called prepare_reinflate, if
    it intends to call reinflate.
