Arun S 9b87551d40 Remove ethernet interface logic for SoftAP and STA 
Issue: The problem is that there is a race condition introduced in that the LWIP thread is relying on the
interface as it is taken down by a application thread while calling disconnect.
In disconnect api called from application context, whd_emac_wifi_link_state_changed() will refer to netif interface
structure in its callback api netif_link_irq(netif). This netif will be cleared by remove_etherent_interface().
whd_emac_wifi_link_state_changed will post message to tcpip_thread. tcpip_thread will process the message and
call the callback api netif_link_irq(netif)
Calling sequence is whd_emac_wifi_link_state_changed -> remove_etherent_interface(). Hence there is a timing issue
that netif might be cleared first before tcpip thread process the message netif_link_irq(netif)

Fix: remove_etherent_interface() will post message to tcpip thread and tcpip:
thread process the message delete_interface()
which will actually remove the inferface from the netif_list.
Calling sequence is whd_emac_wifi_link_state_changed() message post -> remove_etherent_interface() message post.
message processing order netif_link_irq(netif) -> delete_interface().
Since both the processing is handled in single thread, processing of message is handled sequentially.
