hwrng: core - Allocate memory during module init In core rng_buffer and rng_fillbuf is allocated in hwrng_register only once and it is freed during module exit. This patch moves allocating rng_buffer and rng_fillbuf from hwrng_register to rng core's init. This avoids checking whether rng_buffer and rng_fillbuf was allocated from every hwrng_register call. Also moving them to module init makes it explicit that it is freed in module exit. Change in v2: Fix memory leak when register_miscdev fails.
