Subject: babeld: be more explicit about route resize result
X-Git-Tag: frr-5.0-dev~52^2~3

babeld: be more explicit about route resize result

Resizing the route array can fail. Although the error condition is
already correctly handled, if we're more explicit about the variables we
expect to be initialized then clang-analyze is happier.
