[PATCH -next] random: Fix unused function warning

[PATCH -next] random: Fix unused function warning

[YueHaibing]

From: yuehaibing <yuehaibing@huawei.com>

drivers/char/random.c:820:13: warning:
 crng_initialize_secondary defined but not used [-Wunused-function]

crng_initialize_secondary now only used in do_numa_crng_init,
which wrapped by CONFIG_NUMA, so move it to fix the warning.
