From: Zhaoyang Liu <liuzy@xxxxxxxxxxx>
When WLAN interface is up and running, driver unload and
load was causing command timeout error.
We enable Rx data by updating RX ring read pointer in
init_fw_port(). It should be done when FW is completely
intialialised. Command timeout is fixed in this patch by
moving init_fw_port() call to mwifiex_init_fw_complete().
