[PATCH 3/7] sky2: simplify list element error

[Stephen Hemminger <shemminger@vyatta.com>]

[-- Attachment #1: sky2-le-error.patch --]
[-- Type: text/plain, Size: 2017 bytes --]

The code for list element error (which should only happen on hardware
errors) should be cleaner and safer. Gets rid of unused ring_size
argument, which makes next patch easier.
