[PATCH] crypto: bcm/spu2

[Aleksandr Mishin]

In spu2_dump_omd() value of ptr is increased by ciph_key_len
instead of hash_iv_len which could lead to going beyond the
buffer boundaries.

Fix this bug by changing ciph_key_len to hash_iv_len.

Fixes: 9d12ba86f818 ("crypto: brcm - Add Broadcom SPU driver")
