ip: fix error handling in ip_finish_output2()
__neigh_create() returns either a pointer to struct neighbour or PTR_ERR().
But the caller expects it to return either a pointer or NULL. Replace
the NULL check with IS_ERR() check.
The bug was introduced in a263b3093641fb1ec377582c90986a7fd0625184
("ipv4: Make neigh lookups directly in output packet path.").
