mac80211: reset probe send counter upon connection timer reset

Browse source 
Upon beacon loss we send probe requests after 30 seconds of idle
time and we wait for each probe response 1/2 second. We send a
total of 3 probe requests before giving up on the AP. In the case
that we reset the connection idle monitor we should reset the probe
requests count to 0. Right now this won't help in any way but
the next patch will.

This patch has fixes for stable kernel [2.6.35+].
