[PATCH net-next 05/12] netfilter: remove redundant null check before kvfree()

[Florian Westphal <fw@strlen.de>]

From: Subasri S <subasris1210@gmail.com>

kvfree() internally performs NULL check on the pointer
handed to it and takes no action if it indeed is NULL.
Hence there is no need for a pre-check of the memory
pointer before handing it to kvfree().

Issue reported by ifnullfree.cocci Coccinelle semantic
patch script.
