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