netfilter: Fix several warnings in compat_mtw_from_user().
Kill set but not used 'entry_offset'. Add a default case to the switch statement so the compiler can see that we always initialize off and size_kern before using them. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
