There are cases where wl_dev_ioctl returns 0, but the scan was
aborted? That seems incorrect to me. If we
can't trust the error code coming out of the ioctl call, is there
another way to differentiate this case?

In the case I'm covering here, iscan isn't called (iscan_req ==
false). In fact, the wl_do_iscan path works
just fine for me.
