[SVN commits to the DAHDI project]

New Revision: 10210

Log:
wctdm24xxp: Set dahdi_span.devicetype string in one place.

Currently, the devicetype string was set both when the device was first
allocated and updated when an echocanceler was detected. For simplicity,
combine both these steps into a single function.

This change also replaces an improper use of strncat with strlcat.
