[c-nsp] WIC errors

[Seth Mattinen]

Regarding my WIC errors, there's a bug CSCeh30146 about it. Sadly the 
solution is something I figured out on my own. =(

Symptoms: A WIC-1DSU-T1-V2 WAN interface card may become stuck and may 
not detect any alarms or loopback events but may still be able to pass 
traffic.

Conditions: This symptom is platform-independent.

Workaround: Enter the clear service-module serial number command.
