[PATCH -next] net: rfkill: Fix build for the CONFIG_RFKILL_LEDS=n case.

[Paul Mundt <lethal@linux-sh.org>]

Commit ("rfkill: Fix broken rfkill LED in 2.6.30-rc1") sprinkles around
references to rfkill_led_trigger() in the common code, which is only defined
if CONFIG_RFKILL_LEDS is set:

  CC      net/rfkill/rfkill.o
net/rfkill/rfkill.c: In function 'update_rfkill_state':
net/rfkill/rfkill.c:99: error: implicit declaration of function 'rfkill_led_trigger'
make[1]: *** [net/rfkill/rfkill.o] Error 1
make: *** [net/rfkill/rfkill.o] Error 2
