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.

Fixes: eef9b41622f2 ("selinux: cleanup selinux_xfrm_sock_rcv_skb() and selinux_xfrm_postroute_last()")
