Technically here I think you could check that this attribute isn't used
with non-TDLS stations, since in new_station you know what it's going to
be, right?

This is a bit strange? Wouldn't you want to prefer the new attribute, so
you can put some possibly invalid value into the old attribute for old
kernels? Otherwise what's the reason for even reading the new attribute
in this code at all, if new userspace code must set the old attribute
for old kernels anyway?
