[PATCH 2/2] Input: xpad - sanitize xpad_led_disconnect()

[Namhyung Kim <namhyung@gmail.com>]

IMHO kfree() here looks very confusing. xpad_led->name is an array
of char inside struct xpad_led and is not a dynamic memory itself.
But kfree() works well because it is a first member of the struct
so it points start address of the struct and frees the struct.

Change it to xpad_led for the correctness & readability and make
xpad->led NULL for the safety.
