zebra: Prevent Null pointer deref

If the kernel sends us bad data then the kind_str
will be NULL and a later strcmp operation will
cause a crash.

As a note: If the kernel is not sending us properly
formated netlink messages then we got bigger problems
than zebra crashing.  But at least let's prevent zebra
from crashing.
