ofproto-dpif: Fix pointer arithmetic on null pointer.

rule_dpif_lookup() can return a null pointer as 'rule' so we shouldn't
try to calculate '&rule->up' before it's been found to be nonnull.

This doesn't appear to fix a real bug because 'up' is the first member
of 'rule' so when rule is NULL then &rule->up is also NULL.
