nvs_open fails

[jeffsauer]

When compiling using the esp-idf v2.1, I was getting an error saying that nvs_open() failed. Looks like one needs to first initialize NVS now, apparently in previous version the WiFi init did that, but no longer. So, I edited main.c and added the following include:

#include "nvs_flash.h"

and then inside of initialise_wifi() I added:

nvs_flash_init();

just before the call to tcpip_adapter_init();

@jeffsauer Hi, before open nvs, you need to call nvs_flash_init() first.
