["Álvaro Fernández Rojas" <noltari@gmail.com>]

These variables where left as unused in commit 6229c16060fe
("hwrng: bcm63xx - make use of devm_hwrng_register")

Fixes the following warning:

drivers/char/hw_random/bcm63xx-rng.c:85:16: warning: unused variable 'rng'
[-Wunused-variable]
  struct hwrng *rng;
                ^
