crypto: bcm - Fix pointer arithmetic

Browse source 
[ Upstream commit 2b3460cbf454c6b03d7429e9ffc4fe09322eb1a9 ]

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.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
