"aix_chdev" chokes on string attributes

[trickyearlobe]

Cookbook version

2.2.0

Chef-client version

13.8.5

Platform Details

AIX 7.2

Scenario:

Customer complained that he was trying to set the state of en0 to up using the aix_chdev resource, but the resource was complaining there was no attribute state.

The customer verified there is an attribute called state using lsattr -El en0

After a little investigation, we see that the resource requires the attribute to be a lower case Symbol but thats not obvious without some debug which is confusing the customer.

Steps to Reproduce:

Create a wrapper cookbook containing a resource definition as follows:-

aix_chdev "en1" do 
  attributes("state" => "up")
  action :update 
end

Expected Result:

State of en0 gets set to up

Actual Result:

We get a stack trace

Recipe: aix_wrapper::default
  * aix_chdev[en0] action update
