netfilter: remove redundant null check before kvfree()

Browse Source 
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.
