[c-nsp] 3550 crashes upon errdisable recovery from port-security violation

[Joe Maimon]

FYI

Upon recovery from errdisable after port-security violation the switch 
crashes and upon reboot displays the below.

Verified on multiple switches in the 3550 line and that it does not 
occur with 12.2(44), other versions being looked into.
