ap_vlan_open exits hwsim tests

[Eduardo Abinader]

It was a timeout issue in wpaspy:

    def request(self, cmd):
           self.s.send(cmd)
           [r, w, e] = select.select([self.s], [], [], 20)
           if r:

I just increased the timeout and everything went fine. Don't know why do I
need now to do such change, in order to get my tests running ok. A change
in hwsim? I was using latest wireless-testing head for my tests.

Jouni, it is ok if I send you a patch with this incremented value (from 10
to 20)? I've tested with 15 and it failed also.

Cheers.
