Re: [PATCH] Bluetooth: ath3k: enlarge the usb urb timeout

We encountered a issue that the time is not sufficient to load the firmware.

[   14.646698] Bluetooth: Error in firmware loading err = -110,len = 448, size = 4096
[   14.646710] Bluetooth: Loading patch file failed
[   14.646719] ath3k: probe of 3-4:1.0 failed with error -110

And according to the log, it needs 10 times time to finish the transfer,
so, enlarge the timeout 10 times to overcome it.
