[PATCH] networking: fix potential deref-of-null

[ant.v.moryakov at gmail.com]

From: Maks Mishin <maks.mishinFZ at gmail.com>

The initial condition with the OR operator does not guarantee 
that the pointer ci will be non-zero when dereferencing, 
for example, in iproute.c:314: `if (ci->rta_expires)`.
For fix this, the OR operator is replaced by the AND operator.

The trigger was found using the Svace static analyzer.
