iwlagn: move context init after firmware loading
The availability of contexts depends on the firmware capabilities. Currently only the presence of the second context depends on it, but soon P2P support will also be different. Move the context initialisation code to the firmware-dependent setup before registering with mac80211 to make it easier to handle.
