wl1271: Disable connection monitoring while not associated 

The wl1271 does not support disabling the connection monitor feature.
Perform the next best thing by increasing the beacon-loss threshold and
BSS_LOSE event timeout to the maximum values.

This is needed, because we really don't want any random probe-requests during
scanning or especially while in ad-hoc mode and not beaconing.
