Subject: mwifiex: fix failed to reconnect after interface disabled/enabled
From: Amitkumar Karwar <akarwar@xxxxxxxxxxx>
commit c8ccf3ade7851054f82bf88f5fcd393a394038a3 upstream.
Recent patch "mwifiex: fix NULL pointer" skips extended scan event
handling when suspend is in progress. It created a problem for scan
after interface disabled/enabled case.
This patch solves the problem by checking netif_running() status.
