Jouni Malinen 4b9d79b66e tests: Make it less likely to overflow wlan5 control iface socket 
Number of test cases did not read all control interface socket events
from the dynamically added wlan5 interface. This could result in hitting
maximum socket TX queue length and failures in the following test cases.
