dahdi_scan: Support gaps in channel numbering.
If, via the sysfs attributed introduced in DAHDI-Linux 2.5.0, a user has configured spans that do not have contiguous channel numbers, dahdi_scan will not print several of the span attributes in addition to a bad basechan number. This patch allows dahdi_scan to try and get the basechan for a span from sysfs as opposed to calculating based on the number of channels in the previous span scanned.
