netfilter: flowtable: prefer refcount_inc
With refcount_inc_not_zero, we'd also need a smp_rmb or similar,
followed by a test of the CONFIRMED bit.
However, the ct pointer is taken from skb->_nfct, its refcount must
not be 0 (else, we'd already have a use-after-free bug).
Use refcount_inc() instead to clarify the ct refcount is expected to
be at least 1.
