net/compat_ioctl: support SIOCWANDEV

This adds compat_ioctl support for SIOCWANDEV, which has
always been missing.

The definition of struct compat_ifreq was missing an
ifru_settings fields that is needed to support SIOCWANDEV,
so add that and clean up the whitespace damage in the
struct definition.
