Tom Rix 4833ad4908 selinux: initialize proto variable in selinux_ip_postroute_compat() 
commit 732bc2ff080c447f8524f40c970c481f5da6eed3 upstream.

Clang static analysis reports this warning

hooks.c:5765:6: warning: 4th function call argument is an uninitialized
                value
        if (selinux_xfrm_postroute_last(sksec->sid, skb, &ad, proto))
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

selinux_parse_skb() can return ok without setting proto.  The later call
to selinux_xfrm_postroute_last() does an early check of proto and can
return ok if the garbage proto value matches.  So initialize proto.
