wl1271: Fix setting of the hardware connection monitoring probe-req template

Browse Source 
The probe-request template used in the hardware connection monitoring feature
thus far has been an empty one, without the SSID IE and without supported rate
IEs. This causes problems with some AP's.

Additionally, after connected scans, the template for connection maintenance
would remain to be the one last used for scanning - potentially incorrect.

Fix these by getting a pre-filled directed probe-request template for the
associated-to AP from mac80211.
