mac80211: remove struct ieee80211_if_init_conf

Browse source 
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:

@@
identifier conf, fn, hw;
type tp;

tp fn(struct ieee80211_hw *hw,

/**
* struct ieee80211_if_init_conf - initial configuration of an interface
*
* @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.
