netfilter: conntrack: remove uninitialized shadow variable
A recent commit introduced an unconditional use of an uninitialized
variable, as reported in this gcc warning:
net/netfilter/nf_conntrack_core.c: In function '__nf_conntrack_confirm':
net/netfilter/nf_conntrack_core.c:632:33: error: 'ctinfo' may be used uninitialized in this function [-Werror=maybe-uninitialized]
bytes = atomic64_read(&counter[CTINFO2DIR(ctinfo)].bytes);
^
net/netfilter/nf_conntrack_core.c:628:26: note: 'ctinfo' was declared here
enum ip_conntrack_info ctinfo;
The problem is that a local variable shadows the function parameter.
This removes the local variable, which looks like what Pablo originally
intended.
