Ganapathi Bhat f8c095f679 mwifiex: handle race during mwifiex_usb_disconnect ... Race condition is observed during rmmod of mwifiex_usb: 1. The rmmod thread will call mwifiex_usb_disconnect(), download SHUTDOWN command and do wait_event_interruptible_timeout(), waiting for response. 2. The main thread will handle the response and will do a wake_up_interruptible(), unblocking rmmod thread. 3. On getting unblocked, rmmod thread will make rx_cmd.urb = NULL in mwifiex_usb_free(). 4. The main thread will try to resubmit rx_cmd.urb in mwifiex_usb_submit_rx_urb(), which is NULL. To fix this, move mwifiex_usb_free() from mwifiex_usb_disconnect to mwifiex_unregister_dev(). Function mwifiex_unregister_dev() is called after flushing the command and RX work queues.
