[Murilo Opsfelder Araujo <mopsfelder@gmail.com>]

This patch gets rid of the following error when compiling r8192U_core.c
and CONFIG_WIRELESS_EXT is not defined:

drivers/staging/rtl8192u/r8192U_core.c: In function ‘rtl8192_usb_probe’:
drivers/staging/rtl8192u/r8192U_core.c:4697:5: error: ‘struct net_device’ has no member named ‘wireless_handlers’
  dev->wireless_handlers = (struct iw_handler_def *) &r8192_wx_handlers_def;
     ^
