Removed debug message.
Basic Record LED (solid on / off)  action is working. Need to implement blinking LEDs, when pressing any other button.
Removed internal Record LED handling.
Replaced usb_submit_urb() (and tons of code) by hid_hw_request().
ms_sidewinder_led: now calling hid_register_report() to get hid_report.
LEDs are working now!
Bad idea to set initial LED at ms_probe(). We have to find another place to set it.
New method for setting LEDs. Added feature_mapping() hook for setting initial LED.
Fixed set_led spam on feature_mapping().
