iwlwifi: push virtual interface through

Browse Source 
Rather than keeping every bit of information
around in priv and the virtual interface, add
a virtual interface to many functions and use
the information directly from it.

This removes beacon_int, assoc_capability and
assoc_id from struct iwl_priv.
