Subject: mwifiex: fix failed to reconnect after interface disabled/enabled

From: Amitkumar Karwar <akarwar@marvell.com>

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.
