dahdi: Ensure we have room to keep all span channels contiguous.

This fixes a regression from r9609 that Tzafrir reported.  If you
register multiple spans, then remove the first span and try to register
a new span with more channels then the old span, you could end up with
multiple channels with the same number.

This change ensures that spans are ordered and that channels on a span
are always contiguous and ordered in relation to the spans.

In previous released versions of DAHDI (2.4.0 and below) this condition
would result in spans that may not have contiguous blocks of channels.
So it fixes both a recent regression and improves the behavior.
