[PATCH] ARM: 2653/1: Fix memset and memzero macro double-reference of parameters

Patch from Deepak Saxena

The current memset() and memzero() macros on ARM reference the
incoming parameters more than once and this can cause uninted
side-effects. The issue was found while debugging SCTP protocol
and with the specific usage of memzero(skb_put(skb,size),size).
This call would call skb_put(skb,size) twice leading to badness.
The fixed version copies the incoming parameters into local
variables and uses those instead.
