[PATCH 1/2] nl80211: add flag to force passive scan on DFS channels

[Antonio Quartulli <antonio@meshcoding.com>]

In certain circumstances the user might not want to actively
scan DFS channels, therefore add a nl80211 scan flag to
instruct the underlying layers that DFS channels must be
passively scanned.

This flag can be specified upon scan trigger command.
