Make the dscape stack take the driver-supplied channel change time into
account when actively scanning for networks.
This particularly has been a problem in the rt2x00 driver, where
configuration changes are done via a work-queue, and
the subsequent channel changes failed due to the dscape stack scheduling
a channel update while the previous one had not
been performed yet, resulting in failed scans.
