WiFi.begin() fails after WiFi.disconnect() is called

[pablosun]

Cannot connect to another Wi-Fi access point after disconnect() from previous one.

[pablosun]

Cannot reproduce in BSP v0.9.6.

Testing example:

/*
  This example connects to an unencrypted Wifi network.
  Then it prints the  MAC address of the Wifi shield,
  the IP address obtained, and other network details.

  Circuit:
  * LinkIt 7697 HDK
