Vasiliy Kulikov 9871f1ad67 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 a263b30936
("ipv4: Make neigh lookups directly in output packet path.").
