Willem Penninckx c196adf875 HID: usbkbd: synchronize LED URB submission 
usb_kbd_event() and usb_kbd_led() can be called concurrently, but they are not
synchronized. They both readwrite kbd->leds, and usb_kbd_event() originally just
checked the URB status field, while urb.h states that "It [status field] should
not be examined before the URB is returned to the completion handler."

To fix this unsynchronized behavior, this patch introduces a boolean
representing whether the URB is submitted, and a spinlock.
