mwifiex: fix failed to reconnect after interface disabled/enabled

Browse Source 
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.
