wireless: Read scan flags correctly on x86-64
The SIOCSIWSCAN handler is passed data in an iw_point structure. Some drivers erronously use an iw_param instead. On 32 bit architectures the difference isn't noticed as the flags parameter tends to be the only one used by scan handlers and is at the same offset. On 64 bit architectures the pointer in the iw_point structure means the flag parameter is at different offsets in these structures. Thanks to Jean Tourrilhes for tracking this down for orinoco, and Pavel Roskin for confirming the fix and identifying other suspect handlers.
