mac80211: remove struct ieee80211_if_init_conf

All its members (vif, mac_addr, type) are now available
in the vif struct directly, so we can pass that instead
of the conf struct. I generated this patch (except the
mac80211 and header file changes) with this semantic
patch:

- *
- * @vif: pointer to a driver-use per-interface structure. The pointer
- *	itself is also used for various functions including
- *	ieee80211_beacon_get() and ieee80211_get_buffered_bc().
- * @type: one of &enum nl80211_iftype constants. Determines the type of
- *	added/removed interface.
- * @mac_addr: pointer to MAC address of the interface. This pointer is valid
- *	until the interface is removed (i.e. it cannot be used after
- *	remove_interface() callback was called for this interface).
- *
- * This structure is used in add_interface() and remove_interface()
- * callbacks of &struct ieee80211_hw.
- *
- * When you allow multiple interfaces to be added to your PHY, take care
- * that the hardware can actually handle multiple MAC addresses. However,
- * also take care that when there's no interface left with mac_addr != %NULL
- * you remove the MAC address from the device to avoid acknowledging packets
- * in pure monitor mode.
