tests: Make wnm_bss_tm_req_with_mbo_ie more robust

Browse source 
On slow machines or inside VM it may take some time for "DISCONNECTED"
event to arrive. Since the retry delay counter is started already, it
may result in less than 5 seconds time between "DISCONNECTED" and
"CONNECTED" events.

Fix the test by taking more accurate timestamps between the events.
