[PATCH] honor explicit scan requests when disconnected

[Dan Williams]

Even when disconnected, wpa_supplicant should still scan when explicitly
requested to do so via a control interface.  Otherwise, no scans will be
performed after a 'disconnect' command until either a reconnection or a
new network block is selected.  Automatic scanning should rightly be
disabled, but explicit requests should not.

Fix (but not the patch) applies to both 0.6.x and 0.5.x.
