zebra: don't print uninitialized string (3b02fe8)

This crept in as part of the MRIB improvements and I missed the compiler
warning between other noise.  Unfortunately, printing an uninitialised
variable can in fact make zebra crash, so this is not trivial.

Fixes: 3b02fe8 ("zebra: add "show ip rpf" to get result of RPF lookup")
