esp32/network_wlan: Use esp_wifi_set/get_channel to config wifi channel. 

Set the channel with esp_wifi_set_channel(), which adds support for setting
the channel of the STA interface

Get the channel with esp_wifi_get_channel() which returns the actual wifi
channel of the radio, rather than the configured channel.
