wcte13xp: Reset span alarm to RED on startup

Browse Source 
A fresh modprobe and dahdi_cfg would cause a temporary green alarm state on the
driver for a second while the alarm debounced into RED. New logic keeps the
spans alarm state as NONE during the unconfigured state, but sets the alarm
state to RED after the framer reset in the startup logic.
