net: split out ndo_siowandev ioctl
In order to further reduce the scope of ndo_do_ioctl(), move out the SIOCWANDEV handling into a new network device operation function. Adjust the prototype to only pass the if_settings sub-structure in place of the ifreq, and remove the redundant 'cmd' argument in the process.
