[PATCHv2 BlueZ 2/5] plugins/sixaxis: Factor out a set_leds_hidraw() function

[Antonio Ospite <ao2@ao2.it>]

This is in preparation for a set_leds_sysfs() function.

Make set_leds_hidraw() return void, as its return value is never used
by the caller: the setup_leds() callback has to always return FALSE.
---

Changes since v1:
  - Use capital letter after colon in the short commit message.
  - Make set_leds_hidraw() return void, its return value is never used by the
    caller.
