wpa_supplicant: Do not allow too short sched scan

Browse source 
In case that the ssid list is longer than max number of ssids,
ths scheduled scan aborted after timeout and rescheduled again
with shorter timeout and longer interval. In case that the timeout
is shorter than the interval, only one scan iteration will
be run. In this case, go back to the initial values.
