Input: leds - fix out of bound access
commit 6bd6ae639683c0b41f46990d5c64ff9fbfa019dc upstream.
UI_SET_LEDBIT ioctl() causes the following KASAN splat when used with
led > LED_CHARGING:
[ 1274.663418] BUG: KASAN: slab-out-of-bounds in input_leds_connect+0x611/0x730 [input_leds]
[ 1274.663426] Write of size 8 at addr ffff88003377b2c0 by task ckb-next-daemon/5128
This happens because we were writing to the led structure before making
sure that it exists.
