Netfilter fixes for net

The following patchset contains five Netfilter fixes for your net tree,
they are:

1) Silence a warning on falling back to vmalloc(). Since 88eab472ec21, we can
   easily hit this warning message, that gets users confused. So let's get rid
   of it.

2) Recently when porting the template object allocation on top of kmalloc to
   fix the netns dependencies between x_tables and conntrack, the error
   checks where left unchanged. Remove IS_ERR() and check for NULL instead.
   Patch from Dan Carpenter.

3) Don't ignore gfp_flags in the new nf_ct_tmpl_alloc() function, from
   Joe Stringer.

4) Fix a crash due to NULL pointer dereference in ip6t_SYNPROXY, patch from
   Phil Sutter.

5) The sequence number of the Syn+ack that is sent from SYNPROXY to clients is
   not adjusted through our NAT infrastructure, as a result the client may
   ignore this TCP packet and TCP flow hangs until the client probes us.  Also
   from Phil Sutter.
