don't recycle scanf format string if all conversions are done (bug #45808)
* oct-stream.cc, oct-stream.h (scanf_format_elt::special_conversion):
New enum value, no_conversion.
(scanf_format_list::next): If not cycling through the list, return
dummy scanf_format_elt after list has been exhausted.
(octave_base_stream::do_scanf): Only cycle through the format list
more than once if there are conversions to make and the limit on the
number of values to convert has not been reached.
