Johannes Berg 246ed35522 iwlwifi: initial contextification 
In order to support multiple interfaces, we must move
a lot of data into per-context structures so we can
use the contexts the device offers. To start with,
this makes a lot of code context-aware, more changes
will move more things into the context structure.
