Use socket.error instead of non-existent socket.Error

[joren485]

SUMMARY

Use socket.error of non-existent socket.Error.

P.S. No offense, but someone should look into refactoring lib/ansible/module_utils/network/cnos/cnos.py. It is 3.5k lines of hard to read code that contains many pep8 violations.
