wifi: cfg80211: Avoid clashing function prototypes 

When built with Control Flow Integrity, function prototypes between
caller and function declaration must match. These mismatches are visible
at compile time with the new -Wcast-function-type-strict in Clang[1].

Fix a total of 73 warnings like these:

drivers/net/wireless/intersil/orinoco/wext.c:1379:27: warning: cast from 'int (*)(struct net_device *, struct iw_request_info *, struct iw_param *, char *)' to 'iw_handler' (aka 'int (*)(struct net_device *, struct iw_request_info *, union iwreq_data *, char *)') converts to incompatible function type [-Wcast-function-type-strict]
        IW_HANDLER(SIOCGIWPOWER,        (iw_handler)orinoco_ioctl_getpower),
                                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

        [IW_IOCTL_IDX(SIOCSIWGENIE)]    = (iw_handler) cfg80211_wext_siwgenie,
                                          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

        IW_HANDLER(SIOCGIWRETRY,        cfg80211_wext_giwretry),
                                        ^~~~~~~~~~~~~~~~~~~~~~

The cfg80211 Wireless Extension handler callbacks (iw_handler) use a
union for the data argument. Actually use the union and perform explicit
member selection in the function body instead of having a function
prototype mismatch. There are no resulting binary differences
before/after changes.

These changes were made partly manually and partly with the help of
Coccinelle.
