iwlagn: iwl-trans.c can't dereference iwl_priv any more

Browse Source 
This reaches encapsulation for this file. In order to reach this:
 * move priv->valid_context to iwl_shared
 * move the last_rejected initialization to the upper layer
 * define a wrapper iwl_nic_config in the upper layer that calls to
   cfg->lib->ops->nic_config
