wpa: dont send initial "start" message, faster polling interval waiting for connection

the kernel will automatically timeout the eap blocked state
for us and reassociate for us, so there is no need to provoke
the ap to start the wpa/eap handshake.

make the polling faster changing the sleep time from 500 to
100 ms.
